Fostex FF165WK Size:166x166mm

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 FF165WK
