Accuton C220-6-222 Ceramic Bass
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
