S220-6-221

The S220-6-221 is an 8 inch bass driver with ultra stiff ceramic - sandwich 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 S220-6-221 for an application from 31 Hz - 1000 Hz.
