Test Bench: B&C Speakers DE990TN Compression Driver
The compression driver I examined here came from B&C Speakers and is the “little brother” to the titanium diaphragm DE1090TN compression driver featured in the August 2016 issue of Voice Coil magazine. As with the DE1090TN, the DE990TN was coupled with B&C Speakers’ ME90 80° × 60° constant directivity horn. The DE990TN has a 36 mm (1.4”) throat diameter and is driven by a titanium diaphragm with a 86 mm (3.4”) diameter voice coil wound with aluminum wire.
