Test Bench: B&C Speakers DCX464 High Power Coaxial Compression Driver and Horn

The driver to be characterized in this Test Bench is from B&C Speakers and is the DCX464, a pretty unusual ring radiator compression driver. First, because it’s a coaxial compression driver - a rare category of compression driver, and second because the DCX464 compression driver and the accompanying horn measure down to an honest 300 Hz, which is quite a low frequency considering only a few OEM horns on the market go even as low as 400 Hz.

Test Bench: Morel SCW 636 Woofer from The Fat Lady Speaker

This month’s Test Bench includes a very high-end 6″ home audio driver, coming from Morel. This is a hybrid neodymium/ferrite motor, the 6.0″ carbon fiber/Nextel sandwich cone SCW 636, a by-product of the Fat Lady project, Morel’s flagship loudspeaker. Similar to the cabinet utilized in the Fat Lady, the Morel SCW 636 uses a three-layer composite cone and dust cap that combines carbon fiber/Rohacell/carbon fiber that is both lightweight and very stiff.
