The  C220-6-221 is an 8 inch bass driver with ultra hard ceramic  dome.A  FEA optimized  overhung motor design with 38 mm titanium voice coil former guarantees very 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 home stereo bass driver, we recommend our C220-6-221 for an application from 32 Hz - 2000 Hz.
