Accuton C158-6-851

The C158 - 6 - 851 is a 5.5 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 35 Hz – 3000 Hz.
