20% Cancellation fee on

We will therefore charge a
cancellation fee of 20%
of the order price.

S/S Classic 18W 8542.00 Diameter:177mm

Paper Cone Mid/Bass

The 18w 8542 is a 6½" mid/bass utilising a light paper cone, which is coated on the back face to produce a smooth natural bass.

The patented SD-1 magnet system is designed to almost eliminate modulation and dynamic distortion, whilst the low loss linear suspension and foam surround combines dynamic linearity and low colouration.
