Compact studio performance
optimised for bass performance in compact studio monitoring systems
The B220.2 uses a symmetrical field magnet system with a long coil for large linear excursion capability. Double rear suspensions guarantee transient stability at high drive levels. The cone is doped for minimal colouration. The Thiele-Small parameters are optimised for easy use in relatively small enclosures to give extended bass performance.
