N.E.A.R. Returns to the Outdoor Speaker Market

New England Audio Resource (N.E.A.R., which was originally called New England Audio Research) was founded in 1988 by Bill Kieltyka. Interestingly, the company purchased a lot of the transducer tooling from Rudy Bozak, and its line was always based, as with Bozak, on aluminum cone woofers and tweeters. (For a period of time, I designed the networks for the entire N.E.A.R. line of two-channel and home-theater speakers).

The company also originally held the patent for a magnetic fluid technology that replaced the ubiquitous cloth spider to supply compliance to woofers. (Sony is now using this technique in some of its current speaker line ups, following the patent’s expiration.)

Bogen Communications acquired N.E.A.R. in 1997. Bogen kept the name going for a couple of years, but it ultimately closed the company and kept Kieltyka as an employee.

Although the N.E.A.R. name has been absent from the market for more than 14 years, Bogen is bringing it back with a new line of outdoor loudspeaker products.

N.E.A.R.’s first residential lineup in years includes the LB4, the LB5, the LB6, and the LB8, which are all full-range bracket-mount speakers. They will be available in white and black. The lineup also includes the IG 5, the IG 6, and the IG 8, which are full-range speakers designed to be placed on the ground or partially buried. An eighth speaker, the IGS 12 band-pass subwoofer, is also designed to be partially buried. The speakers can be driven by the NEAR 6XL amplifier, which delivers 2 × 600-W output into either 70-V or 8-Ω loads.

In the 8-Ω versions, the bracket-mount LB4, LB5, LB6, and LB8 cost $279, $499, $579, and $679 each, respectively. The 70-V versions for large homes and yards cost $319, $539, $619, and $719 each, respectively. The in- and on-ground IG5, IG6, and IG8 speakers can be used in 8-Ω and 70-V installs and cost $619, $779, and $859, respectively. The partial-buried IGS12 band-pass subwoofer ($1,599) drives either 8-Ω or multi-tap 70-V install. The beehive-shaped IG and IGS models will be available in a terra cotta color.

The speakers and subwoofer can be driven by the 2 × 600-W 6XL amplifier ($1,599) with selectable high- and low-pass crossovers and a low-frequency contour to extend bass performance below 40 Hz. A summing circuit enables stereo material to be combined into both channels.

All four LB speakers feature a patent-pending lever bracket for a tool-free final installation, the company said. The four two-way models use metal-cone spiderless woofers and 1” aluminum inverted-dome tweeters. The coaxial driver arrangement of the LB6 and LB8 and the close proximity of the woofer and tweeter in the LB4 and LB5 provide consistent dispersion for horizontal and vertical placement, according to the company.

The on- and in-ground IG speakers also feature metal cone spiderless drivers, which N.E.A.R. said can operate under water. But the company also adopted a domed woofer design in these models to shed water that may otherwise collect in a cone. The design also improves audio linearity, the company said.

A water-shedding grille prevents moisture from entering “under all but the most extreme conditions,” the company added. The frame of the coaxial-driver assembly also directs away any water that may find its way in, N.E.A.R. added.

The IGS12 subwoofer features a 12” metal cone spiderless driver whose output fires through three horizontal slots about a third of the way from the enclosure’s top. The slots should be located just above ground level when the enclosure is buried. The openings are covered by a stainless grille and hydrophobic fabric.

 


RadioShack Plans Several Store Closings

According to various industry sources and the Wall Street Journal, RadioShack may be about to close about 11% of its stores. The chain is in the midst of a nearly year-long turnaround effort that includes updates of the company’s stores, product assortment, and brand image.

The iconic retailer lost $112 million in the third quarter, its seventh consecutive loss, as it jettisoned unproductive products, and secured $835 million in new financing in December. RadioShack operates about 4,300 stores in the US and 270 in Mexico. Another 1,000 franchised locations are run by independent dealers in the US and franchise operators abroad.

 


B&W Launches New Opening-Price Series

Bowers & Wilkins (B&W) recently unveiled a new opening-price series of in-room loudspeakers that incorporate technology from the company’s higher end lines to improve performance. The 600 series, which began shipping in March, includes the floor-standing 683 ($1,650/ pair), the smaller floor-standing 684 ($1,150/ pair), and the 685 ($700/pair), which can be placed on a stand or a bookshelf. The series also includes the 686 bookshelf ($550/pair), which is the most compact speaker in the series. The HTM61 center channel costs $750 each and the HTM62 center channel costs $450 each. All six models will join a trio of 600-series subwoofers, which will be available in black ash finish.

New technology used in the series includes double-dome tweeters derived from the company’s CM10 speaker. The tweeter features two separate aluminum domes, the second with its center portion cut out. The second dome is glued to the first dome’s rear face to deliver lightness and rigidity.

A new tweeter-decoupling design developed for the 600 series uses a gel ring to physically separate the double-dome tweeters from the cabinet. This prevents resonances from transferring between the baffle and tweeter. The design boosts clarity and delivers “outstanding imaging and dispersion,” according to B&W. The company also added the anti-resonance plugs for mid/bass drivers, used in B&W’s PM-1 speaker, which, again according to B&W delivers smoother response and lower distortion when driven hard.

Another new technology developed specifically for the new 600 series is a dual-layer aluminum bass driver, which features an aluminum bass cone reinforced with a second layer of aluminum around its periphery to deliver more effective damping and a higher break-up frequency to reduce distortion. The dual-layer aluminum design appears in the top floor-standing model.

 


The Bluetooth Speaker Craze Continues

The Bluetooth speaker craze shows no end in sight, which means that more people are listening to music on their smartphones. Here are some of the latest product releases in this category.

MB Quart—Car audio brand MB Quart (acquired by Maxxsonics in 2005) is getting into the portable audio market with the launch of four battery-powered Bluetooth speakers that cost $59 to $199. All products in this new line will be available in April in multiple colors. They feature battery lives ranging from 5 to 12 h. All will come with USB-charging capabilities, hands-free speakerphone capabilities, voice confirmation, and Bluetooth AVRCP to control basic music playback functions on Bluetooth-connected mobile devices.

The QUBOne ($59) features a single driver, a built-in microphone for hands-free calling, and two bottoms, to enable the unit to be placed on its side and keep the controls accessible. The rest have dual drivers but are mono.

The QUBTwo ($99) adds Bluetooth’s secure simple pairing profile, noise-canceling microphone, shock-resistant rubber housing, 8-h battery, and an input jack. The QUBThree ($149) includes a 10-h battery and tethering loop.

The QUBFour ($199) includes a 12-h battery and efficient neodymium magnets that, coupled with an amplifier that operates at a higher voltage, delivers louder sound with deeper bass. The QUBFour also contains dual-source Bluetooth technology to enable two mobile devices to be paired simultaneously to one speaker, making it easier to switch between two mobile devices for music playback. The speaker also includes a 110-V adapter. Apple mobile devices display the speaker’s battery status.

Bose—Bose released the SoundLink III, its latest portable Bluetooth speaker. The third-generation SoundLink Bluetooth speaker features longer battery life, higher output, and a new industrial design.

The $299 model extends playback time of its rechargeable lithium-ion battery by 30%, now lasting up to 14 h. The new model lacks its predecessor’s integrated bi-fold nylon cover, which doubled as a stand that angled the speaker. The new model stands upright on a flat surface. An optional $34 accessory cover is available in gray, blue, green, orange, and pink. The Bluetooth LED signal lights are also new and said to make pairing and switching Bluetooth devices easier. The SoundLink III stores the six most recently used Bluetooth devices in its memory making it unnecessary to pair a previously paired device.

The speaker also features a new DSP algorithm and improved electronics to play louder through four neodymium-magnet drivers and dual-opposing passive radiators, according to Bose. The industrial design has a fingerprint-resistant wraparound metal grille, rounded edges, and a silicone button panel on top to protect it against dirt and dust. The SoundLink III retains an auxiliary input, a microUSB for software updates, and an AC wall charger.

This speaker joins a smaller SoundLink Mini Bluetooth speaker ($199). The first SoundLink was introduced in 2011 and updated in 2012.

bēm wireless—Bluetooth-speaker supplier bēm wireless is launching the Wireless Speaker Band, which is a Bluetooth speaker that’s worn on the wrist and doubles as a hands-free speakerphone. The Speaker Band ($49) incorporates a speaker, a microphone, a spoken audio caller ID, an answer button, and compatibility with most voice-recognition apps. For music playback, it features play, pause, skip, and reverse buttons. Its rechargeable battery delivers up to 6 h of talk time. The device is promoted as a safer alternative to searching through a purse or pocket for a phone, especially if the phone owner is driving. The speaker band is available in six colors: black, white, blue, red, gray, and green. bēm, founded in 2012, manufactures portable Bluetooth speakers, including a boombox-style speaker with an integrated carrying handle.

Pyle Audio—Pyle Audio recently released a shower-friendly portable Bluetooth speaker/speakerphone. The Gator Sound waterproof speaker and speakerphone is a lightweight, waterproof unit with a hook for hanging on a shower head, a built-in microphone for hands-free calling, and a push-button control to connect to any Bluetooth-enabled device. It features a rechargeable lithium battery, a USB charging cable, enhanced bass production, and available in blue, white, or black ($49.99).

 


Majority of Soundbar Sales Below $500

GfK Group, the German market research giant, performed a year-long study of soundbar retail print ads and found advertised prices varied greatly throughout 2013. GfK was founded in 1934 by Professor Wilhelm Vershofen as a Nuremberg, Germany-based scientific institute, “Gesellschaft für Konsumforschung.” It was the birth of institutional market research in Germany.

With its recent study, the research firm noted that 89% of the soundbars advertised were priced around $500; however, as the year progressed, the focus shifted to lower-priced soundbars. In the early part of 2013, 50% of the advertising focused on sub-$300 models. This trend increased with the sub-$300 products comprising 70% of all soundbar advertising, according to GfK.

 


NRF Reports Expect Rise in Retail Sales

Retail sales are projected to rise 4.1% this year, which is somewhat improved over 3.7% gains in 2013. According to a report released by the National Retail Federation (NRF), continued economic growth and an expanding labor market and housing sector will help stoke consumer confidence and expenditures.

NRF’s published data forecasts a real gross domestic product (GDP) growth of 2.6% to 3%, the fastest in three years, and a decrease in the unemployment rate to near 6.5% or lower by December.

In 2014, retailers will be investing in faster fulfillment, mobile payment, in-store mobile marketing, and “name your own price” shopping tools. The sales projection includes most traditional retail categories (e.g., discounters, department stores, grocery stores, specialty stores, auto parts and accessories stores, and non-store categories). The sales projection excludes sales at automotive dealers, gas stations, and restaurants.

The April 2014 Issue of audioXpress is Now Online

AX-2014-04This month’s audioXpress reviews the different approaches in microphone placement techniques for capturing and recording unamplified acoustic music, particularly classical music. A recent study and AES presentation has reignited this issue and our author Gary Galo decided an historical perspective was needed in his article “Stereophonic Recording: What Do Listeners Prefer?”

In our usual review section, we give a listen to the new Focal Spirit Professional Headphones, the first effort of this kind from the prestigious French manufacturer. Miguel Marques tested the Focal Spirit Pros in a quest to discover what this new model brings to an already crowded and very competitive headphone market.

Interested in high-resolution audio? Then you might want to check our Standards Review column, where we examine the recently announced HDMI 2.0 specification. HDMI 2.0 introduces bandwidth support for Ultra HD/4K televisions, adds up to 32 audio channels and 1,536-kHz audio sample frequency with simultaneous delivery of video and audio streams to multiple users.

In this edition, we interview Craig Bernabeu, founder and chief designer of SBS Designs. He created the company with a former colleague to explore “different approaches to record or play back music that would suit my needs” and realize his vision of “US-made high-end designs with a left-field approach available to users,” as he describes it.

Get ready to shake. Mike Klasco’s and Steve Tatarunis’s article discusses structure-borne vibrational energy with “Bass Shakers: Enhancing the Deep Bass Experience with Tactile Energy.”
This month’s Hollow-State Electronics column is dedicated to the “Effects Of Guitar-Amplifier Design On Distortion Sound.” Richard Honeycutt looks closely at one particular amplifier’s design to determine at what stages most of the distortion occurs.

For those interested in DIY projects, you will enjoy a great concept from Michael Rothacher with his LuminAria: A SIT Preamplifier. The author intended this preamplifier to be “compact enough to fit in a suitcase” and a “good-sounding, unusual preamplifier with a spiffy set of performance specifications.” He completed the project in two months, and it was one of the highlights at the Burning Amp Festival in San Francisco.

In our Audio Electronics column, we have Bill Reeve’s take on “An Alternative to Linear Regulators.” In the article, he searches for equivalent power-line ripple rejection with less power dissipation, because no one wants to listen to an audio amplifier that hums.

We also included a book review and this month we share what we can learn from a master by reading The Bruce Swedien Recording Method.

CE Revenues Reach Record High In 2014

Revenues for the consumer electronics (CE) industry are projected to grow 2.4% in 2014, reaching a new record high of $208 billion, according to “The US Consumer Electronics Sales and Forecasts,” the semi-annual industry report released by the Consumer Electronics Association (CEA). The forecast projects that new, emerging product categories will grow by 107% year-over-year in 2014.

These new technology categories, including 3-D printers, Bluetooth wireless speakers, convertible PCs, health and fitness devices, smart watches and Ultra-HD television displays, are cumulatively expected to contribute more than $6 billion to the overall CE industry in 2014. While these emerging product categories represent less than 3% of the entire CE industry, they drive 65% of the total industry revenue growth.

Sales of mobile-connected devices, specifically smartphones and tablets, will continue to contribute significant unit sales and revenue to the total CE bottom line in 2014. Although revenue growth has slowed, unit sales will continue to see steady increases.

Smartphones are expected to maintain their position as the industry’s sales leader in 2014, with unit shipments projected to reach 152 million, up from 138 million units sold in 2013. Additionally, smartphone revenues are expected to generate $41 billion in 2014, a 4.6% increase from $39 billion in 2013.

Unit sales of tablets are projected to reach 89.3 million this year, up from 77.4 million in 2013. Revenues for tablets will reach $27.3 billion this year, up by 3%.

Bright spots within the television category will help drive revenue growth this year, as larger screen sizes and innovative display features have consumers upgrading their video experience. Although total unit sales of displays are predicted to remain even with 2013 levels, total TV sets and display sales are projected to reach $21.3 billion in 2014, up 2% from 2013’s better than expected $21 billion revenue level.
LCD flat-panels continue to dominate the total number of sets sold each year. Both unit sales and revenues for LCDs are projected to increase slightly, with 39 million LCD TVs expected to ship to dealers in 2014, resulting in $19 billion in revenue.

Innovative features such as Ultra HD and organic light-emitting diode (OLED) within the display category are beginning to gain awareness. Unit shipments of ultra-HD displays are expected to surpass $1 billion for the first time this year, while OLED displays will reach $836 million.

Elsewhere in the industry, several other categories are expected to see positive growth in 2014. For the audio industry, soundbars, headphones, and Bluetooth wireless speakers remain the standout products. Soundbar shipments are projected to increase 22% to 3.5 million units and reach $676 million in revenue. Headphones are expected to sell 71 million units, earning $1.5 billion in revenue; while Bluetooth wireless speakers are expected to generate $430 million in total revenue in 2014, a 12% increase year-over-year.

For automotive electronics, the growth of new vehicle sales in 2014 will drive factory-installed systems to reach $11 billion in revenues, an increase of 20%.

For electronic gaming, the release of next-generation gaming consoles is projected to propel unit shipment growth, up 42% year-over-year, to reach revenues of $5.7 billion in 2014.

 


 

Bluetooth Speakers Dominate New Loudspeaker Product Releases

Fujitsu Ten’s Eclipse brand now offers the TD-M1 speakers
($1,300/pair) with Wi-Fi, AirPlay, AirPlay Direct, DLNA, USB B to connect to a PC/Mac, USB A to connect to an iPhone/iPod touch, and a 192-kHz/24-bit DAC.

Fujitsu Ten also introduced a pair of high-end powered subwoofers—the TD725SW MK2 ($7,000) and the TD520SW ($4,500)—and a wireless Airplay speaker. The AirPlay speaker, shaped like the company’s other tapered spherical speakers, is called the TD-M1 ($1,300/pair). The new products ship in February 2014. The company’s current speakers became available in January 2014.

The new audio Eclipse brand entered the home speaker market in Japan in 2001 and has expanded its line to Asia and Europe. Although the brand was briefly in the US some years ago, the Eclipse home audio brand is ready to “properly” enter the US home market in February 2014. Both subwoofers are said to combine power and speed. They use two small-diameter drivers in a back-to-back configuration linked by an aluminum bar. The configuration combines small-diameter driver speed with large-diameter driver power.

Both subwoofers feature Class-D amplifiers, a low-pass filter bypass, an IR remote, and a selector to switch between 5.1- or 2.1-channel inputs. They deliver 500 W and 250 W, respectively, of nominal output with 1% total harmonic distortion (THD). The playback range is 20–150 Hz and 25–150 Hz, respectively. The larger model measures 21.5” × 19.7” × 20.6”.

The AirPlay speaker, which also features time-domain technology, comes with Wi-Fi, AirPlay, AirPlay Direct, DLNA, USB B to connect to a PC/Mac, USB A to connect to an iPhone/iPod touch, and a 192-kHz/24-bit DAC. An iPhone app is available for remote control of power, volume, and input switching.

The DAC provides users the option to remove the oversampling filter during the playback process. Oversampling filters remove noise that occurs when digital sound is converted into analog. The speaker’s oversampling-free mode removes the oversampling filter for enhanced clarity, the company noted.

The speaker features a Class-D amplifier, touch-sensor controls, and a speaker-angle adjustment, which enables users to choose different angles (0°–20°) with a single touch to optimize imaging for a given listening location.

A 3.5-mm input enables connection to TVs and other devices. The speaker measures 6.1” × 8.6” × 9.5” and features ring 3” drivers, a 70-Hz-to-30-kHz frequency response, and 20-W nominal output at 1% THD.

 


 

Atlantic Technology Adds Bluetooth to Its Powered H-PAS Soundbar

While Atlantic Technology (AT) has lowered the price of its PowerBar from $799 to $699, the big news is that the PowerBar now includes Bluetooth capability. The included Bluetooth receiver features nearfield communications (NFC) for tap-to-connect functionality and streams the aptX codec over Bluetooth. The Bluetooth 4.0 receiver connects to the soundbar via the bar’s analog audio input.
The AT product stands out because of its unique H-PAS technology that delivers bass to 47 Hz at “theater-level sound pressure levels (SPLs).” Typical soundbars usually have 150-to-200-Hz capabilities. The H-PAS also improves dialog clarity because of the low woofer excursion that produces less bass distortion. The AT PowerBar also incorporates DSP with Dolby Digital and DTS to deliver a two-to-five-channel experience.

Industry Watch: December 2013

Primax Acquires 70% Share of Tymphany

Primax Electronics, based in Taiwan and founded in 1984, will acquire a 70% share in Tymphany. Hong Kong, China-based Tymphany is an ODM and OEM speaker supplier for home, car, and pro audio brands. The acquisition is expected to be completed by the end of the year following regulatory approvals. Terms weren’t disclosed.

Tymphany has a proven record of success with a healthy margin and balance sheet. The company has been growing at a pace of 40% a year for the past two years. Primax COO Brian Yang said he expects the acquisition to significantly contribute to Primax’s revenues and earnings next year.

Tymphany said it will continue to operate as an independent company but will benefit from the Primax’s technology offerings and manufacturing capabilities. Primax, which is said to be the world’s largest PC peripheral equipment manufacturer, sells products under its own brand name. It is also an ODM and OEM supplier.

Tymphany, with administrative offices in Sausalito, CA, will retain its existing 2,500-employee work force, partner relationships, and management, including Tom Jacoby, chairman and corporate development officer. Tymphany also owns Peerless, an OEM supplier of speaker transducers.

Primax said the acquisition will help expand its presence in the digital audio market, including Bluetooth speakers, digital music players, wireless audio systems, and so forth. “We believe the combined strength of the audio and acoustic technology of Tymphany and the wireless and electronics manufacturing expertise of Primax will put us in the leading position of serving the needs of the digital audio industry,” according to Primax chairman/CEO Raymond Liang.

With the acquisition, Primax also receives a majority stake in several factories and R&D centers in South China. Tymphany’s 2,500 employees are located throughout China, Europe, and the US.

 


AudioXperts Closes Due to Lack of Funding

Luxury-audio startup AudioXperts closed its operations October 11, 2013. However, some of its products may make their way into the consumer electronics (CE) market. Eli Harary, AudioXperts founder and industry veteran, explained that the company’s majority investor, a Taiwan-based company with factories in mainland China, stopped funding AudioXperts after reaching an agreed-upon investment level. The investor decided to discontinue funding even though most of AudioXperts’s delayed product line was coming to market almost a year later than planned.

Unfortunately, AudioXperts reached its investment cap due to design, engineering, and build delays. One product, a TV sound base, was recalled due to quality issues. Other products had to be reworked to meet quality levels. This is not uncommon. coNEXTion Systems, a former CEDIA HT and distributed audio startup, closed for similar reasons (although it did not experience quality control issues).

It seems some Chinese companies that invest in US CE startups don’t understand the way the US does business. This is unfortunate since the potential for success when combining US engineering and marketing with China’s manufacturing can be powerful.

Although Harary explained to the investor’s board that most products were just now coming to market, the board was not willing to continue funding the company. As for the brand’s future, Harary said it is possible, but unlikely, that he will find another investor to operate the company as it was. However, he noted that perhaps the product designs and tooling may be sold to another company that could bring the products to market. AudioXperts attended this year’s CEDIA Expo to promote its new products. Unfortunately, the majority of AudioXperts’ employees have been permanently laid off.

Lenbrook Launches Bluesound Brand

Lenbrook Industries has launched a new brand called Bluesound. The Bluesound designs are the company’s first wireless multi-room audio products, specifically positioned to be a step up from the Sonos brand’s wireless-audio systems in performance and price. Lenbrook, which markets audio components and speakers under the NAD and PSB brands, is pursuing a more limited distribution strategy than Sonos, targeting about 100 A/V specialists. Lenbrook is also exploring an opportunity with Magnolia Home Theater and Magnolia Design Center stores.

Bluesound’s first five products have already been delivered to approximately 40 A/V specialists in the US, primarily current NAD or PSB dealers. After the International CES in January 2014, the company plans to expand distribution to about 100 specialists and possibly Best Buy’s Magnolia Home Theater, which sells NAD and PSB headphones but not NAD or PSB audio components.

An engineering team that included most of Lenbrook’s NAD and PSB engineers developed this new product line, and the company is promoting the new brand’s connection to the NAD and PSB brands’ hi-fi heritage. Bluesound is targeted to music enthusiasts who are unfamiliar with the types of audio components made by companies such as NAD/PSB but who are interested in high-performance audio.

Product development began a little more than three years ago with a mission to create an accurate and musical sounding brand that would attract a broad audience of music enthusiasts, not just audiophiles. The concept was to target music enthusiasts who like the convenience of wireless and are willing to pay more for serious hi-fi performance.

The Bluesound product line includes the $699 Power Node streamer/amplifier, the $449 Node streamer without an amplifier for connection to existing sound systems, the $699 Pulse active biamplified tabletop speaker/streamer, and the $999 Vault streamer/ripper, which also lacks an amplifier. The brand offers the $999 Duo 2.1 speaker system. It can be used with the Power Node, which features an EQ switch to optimize playback through the Duo.

The streaming products, which use Apple and Android mobile devices as system controllers, stream music over a home network via 802.11 b/g/n or via wired Ethernet from a networked PC, Mac, or NAS drive, none of which need to run Bluesound software or use Digital Living Network Alliance (DLNA) technology. The devices also stream music from the brand’s Vault, which combines a wired streamer with a CD ripper, and 1TB of storage for music files ripped in the MP3 and lossless FLAC formats.

All the products also incorporate the TuneIn app, which streams music from radio stations worldwide and from the radio music service. Additional music services will be added as the brand progresses. The Vault also streams from a networked computer, similar to the Sonos motif. When a USB-connected Bluetooth dongle is plugged into the Bluesound streamers, users will be able to stream music from a mobile device to the Bluetooth-connected component, which in turn will retransmit the music via Wi-Fi around the house to the other Bluesound streamers.

Photo 1: Triad Speakers’s new DS700se is a behind-wall, two-way speaker designed for larger rooms or theaters requiring more output and highly dynamic sound quality.

Triad Speakers has released an upgrade to its behind-the-wall Invisible Designer Series Speakers. The new DS700se is Triad Speakers’s first two-way model behind-wall speaker (see Photo 1). It features wider frequency response from 50 Hz to 20 kHz, deeper bass, improved midrange and treble response, and 200-W peak per channel power handling.

The DS700se, which joins seven single-panel models, consists of two separately mounted flat vibrating honeycomb panels per channel, one panel for lows and one for highs.

The other Designer speakers use one full-range panel per channel. As with previous designs, the rigid aluminum-honeycomb panels are cut into the wall, and their paper skins are covered with plaster, drywall compound, or mud skims to completely hide the speakers by blending them into the wall. The DS700se panels fit between the wall studs in typical home construction and require a mounting depth of only 2”.
The flat-panel technology enhances off-axis response when compared with traditional speakers. This is true, in part, because the radiating panels are larger in size than a typical driver, according to Triad engineer David Nelson. Separate placement of low- and high-frequency panels also makes placement more flexible to deliver the best imaging, Nelson added. The high-frequency panel measures 17.7 ” × 13.6” × 1.6” and the low-frequency panel measures 17.7 × 7.9 × 1.6.”

The panel costs $2,250 per channel, which includes a HPF-2 limiter/filter protection unit. For more information, visit www.triadspeakers.com.

CEA Study Shows 38% of Consumers Use Multiple Channels for Purchases

About 38% of brick-and-mortar shoppers end up making their consumer electronics (CE) purchases at retailers’ websites, according to a new CE study. The report, from the Consumer Electronics Association (CEA), also indicates that just under half (45%) of brick-and-mortar customers use their mobile devices to help them shop while in stores, and 4% will use them to make a purchase.

Still, brick-and-mortar stores retain the bulk of visitor business with 69% of purchases. What’s more, 86% of CE storefront shoppers said they use physical showrooms for product examination and returns, and 84% said they make purchases there.

The study also indicated that 89% of CE buyers use retailers’ websites to compare prices and read product reviews, while 84% compare product features online. Among those using mobile devices while shopping in stores, 54% access them to search for product information, 46% compare in-store prices with e-tailers, 42% compare the retailer’s in-store and online prices, and 42% price shop other physical retailers.

The study concluded that 38% of CE shoppers use a physical retailer’s online channels when looking to buy a CE product.

According to Rhonda Daniel, CEA’s senior manager for market research, it is imperative that physical CE retailers have a well-defined multi-channel strategy. Creating seamless and fluid relationships across channels (websites and showrooms) will enable physical retailers to play an integral and uninterrupted role along the entire path to purchase. The complete study, “Multi-Channel Alignment for CE Retailers with Physical Stores,” is available free to CEA member companies at Members.CE.org. Non-members may purchase the study for $999 at the CEA store.

 


Holiday Sales Predicted to Rise

Holiday sales are expected to increase 3.4% from last year, according to a new retail report by the trade group International Council of Shopping Centers (ICSC). The ICSC report maintained that its November to December forecast is up slightly from the 2012 holiday season, even though retailers are anticipating more modest sales. Despite the mixed outlook, and the economy’s “mini-cycle slowdown” over the last three quarters, this year’s holiday sales environment is looking up, according the ICSC.

Along with reduced price discounting, ICSC is also projecting a 13% increase in online and other direct sales this holiday season. Additionally, holiday hiring, which directly correlates to holiday spending and can often help forecast a stronger sales performance, is set to grow 0.5% over last year’s holiday hiring.

The ICSC’s 3.4% forecast comes in right between two previous sales projections. Earlier this month, ShopperTrak, a global retail sales consultancy, projected a 2% increase in holiday sales for November and December, while Deloitte, a financial consulting company, forecasted a gain of as much as 4.5% for the November to January period.

 


NEAR Returns to Consumer Products

New England Audio Resource (NEAR) returned to the CEDIA Expo (September 25—28, 2013 in Denver, CO) for the first time in 14 years to launch a line of all-environment speakers and a companion amplifier for residential applications. Based in Gardiner, ME, NEAR has been focusing on the commercial speaker products following its acquisition by Bogen Communications in 1999. Based in Ramsey, N.J., Bogen Communications is a commercial audio products supplier. Since its acquisition, NEAR’s lineup had been aimed primarily at commercial applications, though NEAR products did sometimes cross over into residential channels when Bogen distributors sold to residential contractors.

Now, NEAR is reentering the residential market, according to NEAR founder and chief product engineer Bill Kieltyka. With consumers growing interest in outdoor audio, NEAR thought it was time to launch an entirely new line designed specifically for the residential contractor.

Although NEAR has essentially been out of the residential channel for more than a decade, the company has been continually advancing its knowledge of what it takes to produce audiophile-grade speakers that can withstand the most brutal conditions in all environments. Developing outdoor speakers for commercial applications enabled the company to take its spider-less, magnetic-suspension metal-cone drivers to new levels of reliability under the most brutal conditions.

The new NEAR residential products include four full-range bracket-mounted speakers—the LB 4, the LB 5, the LB 6, and the LB 8 (see Photo 2). The lineup also includes three full-range speakers designed to be partially buried in the ground—the IG 5, the IG 6, and the IG 8—and the 12” IGS 12 subwoofer.

The new speakers use NEAR-developed spiderless magnetic-fluid suspension woofers. The full-range models are two-way coaxial models with aluminum-dome drivers. The line also includes a 2 × 600-W 6XL amplifier designed for use with the NEAR speaker systems. It features onboard selectable high- and low-pass filters for use in outdoor systems that include a subwoofer. The 6XL drives both 70-V and 8-Ω speakers, thanks to a transformer-less output topography. The LB models are available in black or white. The IG and IGS models are available in a terra-cotta color.

Cosmetically, NEAR’s new speakers feature designs from Allen Boothroyd’s design studio. The LB models, for example, use an unusual lever-locking system and pre-terminated connection leads to make installation and positioning easier and safer.

The IG and IGS models feature a “bee-hive” shape that provides security when partially buried. However, the design also lends itself to freestanding applications.

 


KEF Releases THX Architectural Speakers

KEF officially added its name to the short list of loudspeaker manufacturers that are offering THX-certified architectural speakers (only two other companies—Klipsch and Atlantic Technology—offer THX architectural speakers). KEF’s new products consists of two THX Ultra2 in-wall left, center, or right (LCR) speakers due in January, an Ultra2 round in-ceiling speaker due in December, and an in-wall subwoofer due in January. Two subwoofers used together will qualify for Select2 certification, and four subwoofers will deliver Ultra2 THX performance.

The two three-way LCRs are somewhat unique and use an aluminum front baffle with a perforated-metal bezelless grille. Optional black and white fabric grilles leave a quarter-inch of aluminum exposed around the baffles’ perimeter as an aesthetic option. One of the LCRs, the Ci5160RL-THX, retails for $3,000 each, and the smaller Ci3160RL-THX retails for $1,700 each.

The Ci5160RL-THX contains four 6.5” woofers and a 6.5” midrange with a concentrically mounted tweeter based on KEF’s UniQ design (see Photo 3). The Ci3160RL-THX has two 6.5” woofers and a 6.5” midrange with a concentrically mounted tweeter. The required cutout is 8.2” × 26”. The round in-ceiling speaker is the two-way $800—each Ci1200RR-THX with 8” woofer and concentrically mounted 1.5” dome tweeter. The speaker features a narrow-bezel grille.

The in-wall subwoofer is the Ci3160RLb-THX with three vertically arrayed 6.5” woofers on an aluminum baffle. The $1,000-each subwoofer is matched to a $1,000-each 2 × 250-W KASA500 amplifier that can drive two subwoofers simultaneously. The rack-mountable Class-D amplifier incorporates DSP for active equalization. The amplifier and the subwoofer will be available in January.

 


Artison’s New In-Wall Subwoofers

Artison recently unveiled four new in-wall active subwoofers, all with dual drivers in a reactance-canceling configuration to prevent cabinet and wall vibrations. Non-mass concealing in-wall subwoofers produce cabinet and wall vibrations that reduce audio output and clarity, not to mention disturb people in adjoining rooms. The subwoofers fit flush in standard 2 × 4 walls.

The four models include the $900 RCC 320 PC (see Photo 4) and $1,500 RCC 640 PC, both for preconstruction installations, and the $900 RCC 320 R and $1,500 RCC 640 R for retrofit applications. Their companion subwoofer amplifier is the $800 RCC 620 SA. The amplifier and the 320 models ship in October, and the 640 models ship in November.

They all feature all-aluminum enclosures, IP 65 waterproof rating for high-moisture environments, high-efficiency drivers with extended throw to produce accurate extended bass, and low-profile decorator grilles. The amplifier can drive multiple subwoofers at a time. However, the enclosures are small to increase application options without sacrificing performance, according to the company, which is owned by Cary Christie, one of Infinity’s original founders.

To reduce the size to fit in a standard wall and to provide a reactance-canceling configuration, the RCC 320 PC and RCC 320 R use two pairs of 4” × 6” drivers, while the other two subwoofers use four pairs of 4” × 6” drivers. Each pair of drivers faces each other inside the cabinet, and sound is vented through a horizontal slot in the baffle.

In the preconstruction models, only a narrow grille that covers the vent is visible to homeowners. The retrofit models use larger grilles. The paired drivers are driven in phase so that cone motion is in unison, but physically out-of-phase, thus canceling each driver’s reactive forces, according to Christie. The configuration also enables the use of smaller, lighter, more accurate drivers that are collectively more efficient and have more power handling capacity than a single larger driver. An all-aluminum enclosure was chosen because of its stiffness and thinness, which maximizes interior volume.

The outboard rack-mount Class-D amplifier delivers 400 WRMS into one subwoofer and 600 WRMS into two subwoofers. It features DSP-based preamplifier, music, and movie modes selectable via amplifier IR codes, 0°-to-180° digital phase-shift adjustment, signal-sensing on/off, 12-V triggers, IR jack, balanced XLR input, and adjustable low-pass crossover from 40 to 160 with 12 and 24-dB/octave cutoff slopes.
Separately, Artison is showing a new custom-installed speaker designated for rear- or side-surround applications.

The Mezzanine 8 speaker is designed for in-wall or in-ceiling placement (see Photo 5). It is shipping at $600 per pair. It joins a LRSIW in-wall speaker designated for left, right, and surround applications.
The Mezzanine’s four drivers consist of two mid-woofers and two silk-dome tweeters in a sealed enclosure. The tweeters are mounted at a 60° angle to one another and are wired out of phase to create a nondirectional acoustic pattern above 3 kHz, enveloping listeners “in three-dimensional space,” the company said.

The dual mid-woofers are wired in-phase to generate a point source to provide precise locations for action and reality scenes. The enclosure is molded in ABS plastic with glass fiber for strength and durability. Mounting depth is only 3.5”. It ships with a round, paintable grille for in-ceiling use and an optional square grille for wall placement.

Powersoft D-Cell504 IS Modules Drive Unique “Wall of Bass”

Wall Of Bass

Wall Of Bass

Powersoft D-Cell504 IS high-power amplifier modules have been designed to drive a unique “Wall of Bass” (as low as 7 Hz) in an Austrian nightclub.

The newly-reconstructed Club SUB, in the city of Wiener Neustadt, set out to integrate a perfect low-frequency solution, capable of reproducing a wide range of live and DJ-derived music (e.g., Drum ‘n’ Bass, Dubstep, and Techno) and arts presentations, as well as workshops and theatrical performance in a completely revolutionary way.

And since the 300-capacity club is located in a heavily populated residential area emphasis needed to be placed on acoustic isolation.

Project managers, Wolfgang Sauter (from Pro Performance) and Reinhard Nell (from Lambda Labs), were equal to the challenge.

Lambda Labs German-based director, Steffen Kroschel, said, “The owners’ goal was to achieve a similar sound performance as it had in the Grelle Forelle Club in Vienna. Given the concerns of local residents, when Mr. Sauter surveyed the building, with its tube like architecture, the abstract idea of a ‘vibrating wall’ became more logical.”

He contacted Lambda Labs where Richard Nell supported the concept with simulation data, parameters, and measurements— applying his knowledge of high-performance concrete “closed box” enclosures and amping. The drivers were developed especially for this application, going through 10 prototype stages, while the club owners helped with casting the concrete loudspeaker enclosures.

For the rear wall, behind the 6 m × 5 m stage, 400-kg special concrete blocks were cast and set into a 6 m × 3 m wall, using 13 tons of heavy concrete and a further 35 tons for the foundation—requiring a monumental effort. “It was extremely difficult to handle these enclosures with small forklift trucks and build the 50 cm deep low-frequency absorber,” said Kroschel. “Behind the wall is sand, and under the wall, Mr. Sauter chose material that is used for highway construction.”

Each concrete block serves as a loudspeaker enclosure with a pressure-resistant rear chamber that implements the perfect impulse response of a “closed-box” design and maximizes the radiation resistance of the woofers through the acoustically hard surface. A self-enveloped 15” speaker was produced and adapted to the unusual demands of this project. The single chassis are designed to act together like one single swinging wall—in a similar principle to a piston in a cylinder.

Kroschel explained, “A perfect plane wave is created in the interior of the club, which naturally moves along the side walls and doesn’t induce any room modes. The rear of the main floor was converted into a single bass trap to absorb the incoming wave. The SUB thereby achieves an acoustical result that could never be reached even outdoors.”

Outside, virtually no noise escapes. And Nell and Sauter, agree that “such an operating range and evenness of the low frequencies is overwhelming.”

But to achieve this optimum performance, every driver needed be powered by its own dedicated amplifier module to take advantage of the shortest cable runs, matching power supplies, and impedance data. Nell chose Powersoft, a longtime partner of Lambda Labs, to provide amping for the “Wall of Bass.” Lambda Labs supported the installation with items like amplifier mounting frames.

The 32 Lambda Labs OEM CX 15” ultra-long excursion drivers, with ± 25-mm linear excursion capability, are set in housings made from special concrete. Each is driven by 800-W amplifying modules, with the maximum desired sound pressure level (SPL) reached at an excursion of only ±3 mm. Therefore, the “Wall of Bass” only uses 500-W peak music power during operation, which sets new standards of energy efficiency.

Via their two-channel 32 D-Cell504 IS amp modules, Powersoft delivered 25,600-W amping power, including four-in voice coil with a custom-made venting system that has a hardened membrane.

Integrated within an aluminum heatsink panel, the D-Cell504 IS provides an interface panel with input volume potentiometer, double XLR for mono input and link out or stereo input operation, four LEDs for limit, clip, signal, and ready, with a four-LED preset selection button to show the preset in use. Easy access to the DSP mounted on board, is further facilitated via remote control capabilities provided by Powersoft’s proprietary Armonía Pro Audio Suite.

New Intelligent Amplifiers for the Install Market

Lab.gruppen, a pioneer in the DSP integration concept and amplifier control, recently introduced the new localized utility compact intelligent amplification (LUCIA) decentralized installation amplifier range.

Putting power and audio processing where it is required, Lab.gruppen’s LUCIA is a compact, two-channel, Energy-Star compliant, Class-D amplifier platform. Designed with installation speed and easy configuration in mind, LUCIA combines cutting edge low-impedance amplifier electronics with advanced DSP into the smallest amplifier the company has produced.

LabGruppenRS7866_LUCIALUCIA is designed for small-scale AV applications where high-quality audio is required, without the complication and additional cost of a distributed system with centralized rack-mounted amplification, matrixing, and processing. LUCIA also offers system designers a logical and cost-efficient solution that is ideally suited for corporate boardrooms, classrooms, small lecture theaters, museum multimedia areas, and retail units.

The company offers four models with two power configurations—2 × 60 W and 2 × 120 W—each available with either a four-in, four-out matrix-mixer and configurable DSP features (LUCIA 120/2M, LUCIA 240/2M) or in a basic two-in, two-out configuration (LUCIA 120/2 and LUCIA 240/2). While all the models are equipped with DSP pre-configured “out of the box” for operation in typical applications, the Matrix variants also facilitate easy setup via USB connection (with Windows and Mac LUCIA configuration software) to meet specific system requirements.

Its new Enhanced Bass Profile, a DSP feature, delivers improved low-frequency performance from standard full-range in-ceiling or surface-mount loudspeakers, which may negate the need for a separate subwoofer.

These amplifiers also offer an Auto Load Sense feature, in which the device automatically measures a connected loudspeaker load’s impedance and adjusts itself to deliver full power at all impedances (2 to 8 Ω).

All LUCIA models also come with intelligent fan control for silent operation at low volumes and low noise even at high output when the fan is operational.

Each LUCIA model could conceivably drive up to 16 speakers on a localized low-impedance system (eight per channel if the loudspeakers were 16 Ω).
