SB Acoustics Launches Much Anticipated 9.5-Inch Satori TeXtreme Woofers

The SB Acoustics Satori TeXtreme range using Thin-ply Carbon Diaphragms (TPCD) has now expanded to four sizes. So far the biggest commercially available TPCD driver using the increasingly popular technology, the SB Acoustics Satori 9.5" woofer with a 2" voice coil, is now available in 4 and 8 ohm variants. The thunder from the extended bass response of the new model WO24TX-4 and model WO24TX-8 woofers will no doubt be soon felt at hifi shows all over the planet.

The Satori MW19TX-8 TPCD cone 7.5" woofer is the fourth TPCD diaphragm transducer to be explicated in Test Bench, the first being an Eminence compression driver and the remaining all woofers from SB Acoustics. The high-end MW19TX-8 has a substantial feature set with similar features as the rest of Satori series with TPCD cones, impressing immediately by its distinctive cosmetics and subjective performance, which this characterization illustrates.

Perlisten Audio — the audio company founded by an all-star team of industry professionals, which had to wait almost three years to show the results of its development efforts due to the global pandemic — has announced the new S5t tower speaker, a slightly smaller version of the company’s flagship S7t. Like its larger sibling, the S5t is a THX Certified Dominus speaker that serves as a missing link between large home A/V speakers and full-size models created for leading movie theaters across the globe.

This article details the Composite Sound journey that led to the extensive use of TPCDs for loudspeaker applications and the company's second-generation Metamodal technology. This new engineering approach allows designing loudspeakers tailored for an intended purpose, realizing a physical representation of a TPCD computer-simulated model that is only achievable through the company's unique proprietary production process.

TPCD is the acronym for Thin-Ply Carbon Diaphragm, which is essentially the technology developed in Sweden by Oxeon to create a new-generation material with properties that are now well-proven for speaker cones and domes. The Satori MW13TX-4 TPCD cone 5” woofer is the fourth TPCD diaphragm transducer to be explicated in Test Bench, and this one has a substantial feature set, including a single piece bowl-shaped TPCD cone and NBR surround. This article was originally published in Voice Coil, January 2022.

The February 2022 edition of Voice Coil is now available and brings the latest information about speaker diaphragms and all the innovations in cones, domes, and surrounds. Martin Turesson tells the story of Composite Sound and its second-generation Metamodal TPCD technology, while Mike Klasco discusses advancements in materials and processes for speaker diaphragms and surrounds. And in Test Bench, Vance Dickason characterizes the latest Satori MW19TX-8 midbass woofer by SB Acoustics using TPCD (TeXtreme) technology, before addressing the latest Industry updates.

PerListen Audio, a new audio company founded by an experienced team of industry professionals, announced its intention to develop and bring to market a full line of THX Certified loudspeakers, bridging the gap between large home theater speakers and those used in movie theaters worldwide. All the new PerListen speakers feature state-of-the-art drivers, including beryllium tweeters, TexTreme woofers and carbon fiber midranges with advanced waveguides, all designed using advanced Comsol acoustic modeling.
