Test Bench: The 10NW76 Pro Sound High SPL 10” Driver from B&C Speakers

The driver on this Test Bench is from B&C Speakers and clearly designed for professional audio.

It uses a proprietary 12-spoke (six double spokes) cast-aluminum frame with a series of cooling vents that allow air to move past the voice coil and across the front side of the neodymium motor assembly. The cone assembly consists of a curvilinear waterproof coated paper cone and dust cap. This article was originally published in Voice Coil, December 2021.
