The MR16P-4 6.5” Satori Midrange from SB Acoustics

The subject of this Test Bench is the recent SB Acoustics 6.5” MR16P-4 Satori midrange, which is nominally a midrange version of the SB Acoustics MW16R-4 (first reviewed in the November 2011 issue of Voice Coil) with higher sensitivity and shorter Xmax. The original Satori MW16R, while looking cosmetically similar to the Scan-Speak Illuminator 18WU series, was a well-designed driver that has established itself as a true high-end home audio competitor.

Test Bench: Dayton Audio DSA175 Designer Series 6.5” Woofer

This month’s Test Bench samples came from US OEM, Dayton Audio. I received a home audio 6.5” woofer, the DSA175, from the brand’s popular Designer Series of aluminum cone woofers. Each product in this line incorporates proprietary stamped steel frame with a thin mounting lip that enables front mounting without insetting the driver (surface mounted), high relative XMAX, with paper cones for the DS series and aluminum cones for the DSA series.

Test Bench: B&C Speaker 8MBX51 Midbass Woofer

Test Bench: B&C Speaker 8MBX51 Midbass Woofer

This month’s Test Bench is part of B&C Speakers' MBX series of mid-bass woofers, the 8MBX51. The MBX series offer acoustic designers a new range of high efficiency, wide bandwidth alternatives that were not previously available from B&C Speakers, and are especially well suited for two-way loudspeaker applications. Features for the 8MBX51 are fairly impressive. Cosmetically speaking, this is also a good looking driver. This article was originally published in Voice Coil, November 2016.

Test Bench: Faital Pro HF108R Compression Driver

Test Bench: Faital Pro HF108R Compression Driver

This month’s Test Bench samples came from a premier Italian Pro Sound OEM driver manufacturer. From Faital Pro, I received the HF108R compression driver coupled with a LTH102 60° × 50° horn. The HF108R is the latest in Faital Pro’s series of Ketone Polymer diaphragm 1” compression drivers. I reviewed the HF108 compression driver in April 2015, and included some data on the HF108R. However, this transducer is different enough that it deserves a separate review. This article was originally published in Voice Coil, November 2016.

Test Bench: Wavecor SW223BD03 8.75-Inch High XMAX Subwoofer

For this Test Bench, Vance Dickason characterizes Wavecor’s new 8.75” high XMAX subwoofer, model SW223BD03. As Dickason reminds us, this new subwoofer is part of the brand's rather extensive line of subwoofers — ranging in size from 2.75” to 12”. Voice Coil featured the 4 Ω version of this device, the SW223BD02, in the April 2015 issue. Wavecor’s SW223BD03, which is the 8 Ω version. This article was originally published in Voice Coil, October 2016.

Test Bench: Tymphany GBS-135F25AL02-04 5.25-Inch Woofer

Test Bench: Tymphany GBS-135F25AL02-04 5.25-Inch Woofer

The driver I received for testing in this edition of Test Bench came from Tymphany, and is a patent-pending thin profile 5.25” aluminum cone mid-woofer from the company’s GBS line of thin profile woofers and midranges. Features for the GBS-135F25AL02-04 include a four-spoke stamped steel frame with a mere 27.4 mm (1.08”) total depth. The depth is significant as the motor assembly is obviously housed inside the frame. This article was originally published in Voice Coil, September 2016.

The B&C 21DS115-8 is rated at 1,700 WRMS with a continuous power handling rated at 3,400 WRMS. The 21DS115-8 weighs in at a modest (for an 21” woofer!) 32.8 lb.
