Hard Paper Cone Mid/Bass

The 21w 8555 is an 8" bass utilising a hard paper cone, which is impregnated and coated to dampen the resonance normally associated with stiff cones.

The patented SD-1 magnet system is designed to almost eliminate modulation and dynamic distortion, whilst the low loss linear suspension and rubber surround reduces compression and combine to produce dynamic linearity and low colouration.
