Accuton C158-6-851 6.25" Ceramic Cone Mid/Bass driver.

The C158-6-851 is a 6.25 inch bass - midrange driver with ultra hard ceramic dome. A FEA optimized overhung motor design with 38 mm titanium voice coil former guarantees extraordinary low energy storage and good heat transfer. The low loss rubber surround and a thin fabric spider center the moving parts with high linearity. As a typical small home stereo bass - midrange driver, we recommend our C158-6-851 for an application from 45 Hz - 3000 Hz.
