Volt BM220.8 Bass-mid Unit

8" Doped Paper Cone Mid/Bass

The BM220.8 combines powerful bass performance with extended low colouration midrange. It uses a symmetrical field magnet system for large linear excursion capability and the double rear suspensions guarantee transient stability at high drive levels. The plastic cone is critically doped for minimal colouration.

The Thiele-Small parameters are optimised for easy use in relatively small enclosures to give extended bass performance.
