Test Bench: B&C Speakers 1” DH450-8 Compression Driver
The DH450-8 ultra-compact compression driver from B&C Speakers incorporates a 1.7" high temperature Polymer diaphragm driven by a 44mm voice coil wound with aluminum wire on a high Qm Kapton former. Its most fascinating feature is the patent-pending phase plug with a deliberately twisted internal channel, which is intended to improve the overall frequency response. For this characterization, the DH450-8 1" neodymium driver is measured along with the B&C Speakers ME10v2 90x60 hyperbolic cosine flare horn, made from injection-molded ABS.
