it is unlikely that we could sell it to

cancellation fee of 20%
of the order price.

Fostex FF85WK Size:83x83mm
KENAF Paper Cone Full Range
The FF-WK series utilises a double layer paper cone, consisting of a wood pulp fibre base and a KENAF paper surface layer. Which along with a dome shaped aluminium centre cap and pocket neck damper, ensures a fast, realistic high quality sound throughout the range.
Exclusively designed for use in bass reflex enclosures, the FF-WK series offers designers a chance to use a full range drive unit in a relatively small cabinet, without compromising on sound quality.
A cabinet kit is available for the FF85WK
