Test Bench: A Redesigned DE990TN-8 1.4” Compression Driver from B&C Speakers

The compression driver/horn that I received for testing in this edition of Test Bench was the redesigned B&C Speakers DE990TN-8, a 1.4” neodymium motor compression driver with a titanium diaphragm coupled with the ME90 horn. This article was originally published in Voice Coil, September 2016.

In this Test Bench, Voice Coil characterizes two high-end compression drivers and horns from Eminence, the N314T-8 with the H14EA horn, and the N320T-8 with the H2EA horn. Both these neodymium motor compression drivers from Eminence share pretty much the same feature set. The main difference is the N314T-8 is configured for a 1.4” throat, and the N320T-8 is configured for a 2” diameter throat. This article was originally published in audioXpress, March 2016.

Reinforcing its pro audio solutions portfolio, Celestion introduced two new ferrite magnet compression drivers at NAMM 2016. The CDX20-3020 is a new 2-inch exit compression driver with a high-performance titanium diaphragm, while the new CDX1-1070 is a 1-inch exit ferrite magnet compression driver purpose-built for compact two-way systems.
