Accuton 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
