C220-6-222

The C220-6-222 is an 8 inch bass driver with ultra hard ceramic dome. A FEA optimized overhung motor design with 55 mm titanium voice coil former guarantees very low energy storage and good heat transfer. Its high force factor leads to outstanding transient response for more realistic reproduction. The low loss rubber surround and a thin fabric spider center the moving parts with high linearity. The recommended application for this excellent bass driver is from 32 Hz - 2000 Hz.

Highlights:

8.5 inch bass-midrange with high efficiency for 2 or 3-way designs
large sized voice coil with 55mm titanium voice coil former for high midrange resolution
big, underhung 120mm Neodymium magnet system for very low distortion
