Bespoke Cabinets



Let us help you design unique
bespoke cabinets for
your loudspeakers.

Our cabinet-maker can produce
individually designed cabinets to a
high quality furniture finish.

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.

A demonstration room is available 
at our premises for you to listen
to a selection of our loudspeakers.

You are welcome to bring your own
source equipment in order to replicate
your usual listening conditions

Fostex FF125WK Size:117x117mm

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 FF125WK
