10" Paper Cone Bass
The B250.8 features a symmetrical field magnet system and long voice coil for large linear excursion capability. The double rear suspensions whose characteristics are matched to that of the motor assembly and linearity at drive levels. An extended pole piece is utilised to minimise distortion inducing inductance swing at high power levels.
The Thiele-Small parameters are optimised for powerful extended bass performance.
