This month, in Voice Coil, read our AISE 2018 Report, Christopher Struck discusses "Efficiency Bandwidth Product for Loudspeaker Drivers," and James Croft reviews a patent originally claimed in 2013 on a Double Coil Speaker design, now granted to Friedrich Reining (Vienna, Austria), on behalf of Sound Solutions International from China. In this month's Test Bench, Dickason examines two 1" compression drivers: a new PEEK diaphragm compression driver from Precision Devices, the PD.CD1N, and the Peerless by Tymphany DFM-2544R00-08.

The DFM-2535R00-08 compression driver I examined this month came from Tymphany. This is the first compression driver in the company’s new three model compression driver line from Peerless by Tymphany. The DFM-2535R00-08 has a 1” throat exit diameter and a 1.4” titanium diaphragm with a polyimide surround. This is driven by 35.5 mm diameter voice coil wound with round copper wire on an aluminum former (ASV). This article was originally published in Voice Coil, August 2017.

Peerless by Tymphany announced that its STW-350F188PR01-04, a 15” subwoofer built for high-performance HiFi applications, previously previewed at trade-shows, is now available for distribution as part of the brand's catalog. The new STW-350, features an 8” voice coil, triple suspension, and a dual-spider design, providing superior low-frequency performance in a smaller-than-traditional enclosure.

As Voice Coil celebrates its 31st anniversary, our November 2017 edition reflects on its heritage and jumps directly to the future of speaker design with an exciting Test Bench of two full-range drivers from the Peerless by Tymphany PLS Line - precisely the ones that are now powering some of the so-called smart speakers. This edition also features a complete directory of Measurement Microphone vendors.

The newest product line from Peerless by Tymphany is the SDF series of woofers, with sizes ranging from 10-15”, built for more bass in smaller-than-traditional enclosures.

As a result of a new distribution agreement, Peerless by Tymphany’s high-end drivers are now available globally through global electronic components distributor Digi-Key Electronics.
