Product details
Accuton C220-6-221 Bass-midwoofer
The Accuton C220-6-221 is a high-quality bass-midrange driver with an ultra-hard ceramic dome. The driver has a medium-sized voice coil with 38mm titanium voice coil former for high midrange resolution. The driver has an overhung motor design which means that the voice coil is longer than the magnetic gap. This design allows for better control of the diaphragm movement and reduces distortion.
