Test Bench: B&C Speakers' 12FCX76 12” High-Performance Pro Sound Coaxial
December 26, 2018 by Vance Dickason

Test Bench: B&C Speakers' 12FCX76 12” High-Performance Pro Sound Coaxial

This edition of Test Bench characterizes the 12FCX76, 12” high-performance pro sound coaxial from B&C Speakers. This coaxial driver is similar to the 12FHX76, where the “H” designates that it uses a horn-loaded compression driver, while the “C” in the 12FCX76 stands for conical-loaded compression driver (the “F” is for ferrite). The 12FCX76 uses ferrite motors for both the woofer and the compression driver. In terms of features, the 12FCX76 woofer is built on a 12-spoke (six twin-leg spokes) cast aluminum frame with eight mounting holes. This article was originally published in Voice Coil, July 2014.

Test Bench: The Peerless by Tymphany PMT-40N25AL01-04 Mini Full-Range Driver

The 1" diameter full-range drivers are among the most used transducers in consumer electronics. They are finding broad use in numerous Bluetooth speakers. The driver submitted by Tymphany for this Test Bench fits into that category. The Peerless by Tymphany PMT-40N25AL01-04 is a 25-mm (1”) diameter full-range driver built on a proprietary injection-molded two-piece polycarbonate (one piece for the motor assembly structure and one piece for the protective grill). This article was originally published in Voice Coil, July 2014.

Test Bench: Two 28 mm Dome Tweeters from Dayton Audio: RST28A-4 and the RST28F-4

In this Test Bench, I characterized two new 28 mm dome tweeters from Dayton Audio — the RST28A-4 and the RST28F-4 from the Dayton Reference Series. Both are similar tweeters that share pretty much the same platform with the primary difference being the RST28A-4 uses an 30 mm aluminum dome and the RST28F-4 has a 30 mm coated silk dome. This article was originally published in Voice Coil, September 2018.

Test Bench: Dayton Audio Epique E160CF-8 Midbass Driver

This Test Bench characterizes the new Dayton Audio Epique E160CF-8 midbass driver, from the company’s new Epique high-end transducer line. This new 5.25” midwoofer is Dayton’s entry into the ultra-high-end driver market. Dayton built it with the intention of competing with the likes of SEAS, Scan-Speak, Eton, Accuton, and Morel. Applications for the E160CF-8 include use as a midrange in a multi-way speaker or as a woofer in a two-way speaker. This article was originally published in Voice Coil, September 2018.

Test Bench: B&C Speakers DE780TN-8 Compression Driver
November 14, 2018 by Vance Dickason

Test Bench: B&C Speakers DE780TN-8 Compression Driver

For this test bench article, I characterized the DE780TN, a 1.4" exit titanium diaphragm pro sound compression driver from B&C Speakers. This compression driver is one of the latest additions to B&C Speakers’ extensive 17-model ferrite and neodymium motor 1.4" exit compression drivers. B&C Speakers supplied the ME90 horn for use with the DE780TN-8. This constant directivity horn has a 1.4" exit bolton type made from cast aluminum, and provides an 80° × 60° coverage pattern and a 900 Hz cut-off frequency.

Test Bench: TPL75 Compact Pro Sound AMT from Acustica Beyma

Test Bench: TPL75 Compact Pro Sound AMT from Acustica Beyma

The TPL75 is one of the Air Motion Transformers (AMT, aka Air Velocity Transformer) that Acustica Beyma has developed for pro sound applications. Part of the success of Beyma’s AMTs for pro sound comes from its proprietary X-Bow technology, which opens as much as possible the mechanical constraint in the diaphragm, allowing it to manage higher temperatures, increasing the limit of the power the diaphragm can handle.

Test Bench: The Alpha-5-8 5" Midbass Driver from Eminence

For this test bench article, I characterized the New Eminence Alpha-5-8 5” line array/column array midbass driver. This a new 5” midwoofer from the American Standard Series, a 24-model transducer line of epoxy-acrylic finished stamped frame woofers and midranges. Applications for the Alpha 5-8 include use as a midrange in a multi-way speaker, as multiples in a line array, or as a compact column PA speaker.

Test Bench: Tang Band W3-2088SOF Micro Home Audio Subwoofer
October 17, 2018 by Vance Dickason

Test Bench: Tang Band W3-2088SOF Micro Home Audio Subwoofer

This a Test Bench of Tang Band's W3-2088SOF, a high XMAX 3.5" home audio RBM Micro subwoofer. The W3-2088SOF is built on an injection-molded eight-spoke frame that supports an unusual rectangular housing. The really unusual feature is that the W3-2088SOF does not use a spider. Instead it gets its compliance from two surrounds like a dual spider configuration. The voice coil former is vented below the inside diaphragm and also vented between the two diaphragm. This article was originally published in Voice Coil, January 2014.
