S/S Classic 18W 8535.01 Diameter:177mm

Carbon Paper Cone Mid/Bass

The 18w 8535 is a 6" mid/bass utilising a carbon 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 combines dynamic linearity and low colouration.

This drive unit is ideal for larger bass reflex enclosures, where it is capable of producing very deep and precise bass.
