20% Cancellation fee on
made-to-order products.

If you decide to cancel your
made-to-order speaker for any reason,
it is unlikely that we could sell it to 
another customer at full selling price.
We will therefore charge a
cancellation fee of 20%
of the order price.

S/S Revelator 18W 8531G00 Diameter:182mm

Sliced Paper Cone Mid/Bass

Utilising Scanspeak's revolutionary sliced paper cone, the 18W 8531G00 produces a clean, dynamic sound with low distortion and a good transient response.

The ultra long throw voice coil uses aluminium wire wound onto a paper reinforced Kapton former along with Scanspeak's patent "Grasshopper" chassis, allows the 18W to produce a bass response of unusual depth and quality.
