Test Bench: BMS 4507ND Dual Diaphragm Coaxial Planar Wave Driver

The BMS 4507ND is a unique transducer that uses a neodymium coaxial compression driver to drive a planar waveguide intended for use in line arrays. BMS Speakers patented the two-way compression driver technology in 1997. This month’s Test Bench subject, the 6.5” 4507ND features a 300-Hz to 22-kHz bandwidth (6 to 22 kHz for the tweeter and 400 Hz to 6.3 kHz for the midrange). The rectangular planar waveguide is optimized for 0° to 15° vertical dispersion and up to 120° in the horizontal plane. This article was originally published in Voice Coil, May 2014.

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: The 951PB 1.4" Compression Driver from Radian Audio Engineering

In this Test Bench, Vance Dickason looks at an interesting new high-frequency transducer: the 951PB, a 1.4” exit pro sound compression driver from Radian Audio Engineering, based in Orange, CA. The 951PB shares an almost identical feature set with the existing 950PB. Both have neodymium ring magnet motors, high temperature 101.6 mm (4”) diameter polyimide voice coil formers wound with copper-clad aluminum-edge wound ribbon wire voice coils. This article was originally published in Voice Coil, July 2018.

Test Bench: Radian Audio Engineering 950PB and 760NEOPB Compression Drivers

September 20, 2018 by Vance Dickason

Test Bench: Radian Audio Engineering 950PB and 760NEOPB Compression Drivers

This was the first time Test Bench featured a product from the highly respected Radian Audio Engineering. Radian sent the 950PB and the 760NEOPB, two of the company’s flagship compression drivers. The 950PB and the 760NEOPB share several features. They are both 2” exit compression drivers, with a useful response above 10 kHz. The 950PB and the 760NEOPB use neodymium motor structures and pure aluminum diaphragms with a proprietary mylar suspension that greatly reduces second- and third-order harmonic distortion. The two transducers mainly differ with regard to their voice coil diameters. This article was originally published in Voice Coil, November 2014.
