F50 Walnut Prototype Cabinets Pair

Prototype F50 2-Way Bookshelf Speaker Cabinets (Pair) – Walnut Finish

Price: £175.00 / pair

(Limited Availability – Only 3 pairs)

A rare opportunity to acquire a pair of high-quality development F50 prototype cabinets finished in real walnut veneer. Ideal for DIY hobbyists, custom speaker builders, and audio enthusiasts looking for premium enclosures for a classic compact monitor project.

These enclosures are designed as a 2-way rear-ported system (rear port tubes included) and come fully damped internally with fitted acoustic foam. The front baffles are factory cut to house the classic driver combination of a B110 (5" / 127mm) mid/bass unit and a T27 (¾" / 19mm) dome tweeter.

Front baffle cutout has been pre-routed (rebated/recessed) to the exact thickness of the driver's outer chassis flange. The B110 drops straight in from the front and sits flush with the baffle surface without needing an external spacer, bezel, or trim ring. You can mount the drivers using standard metric M5 machine bolts/screws, providing a secure, reusable mechanical grip that won't strip or weaken the wood when tightening or removing the drive units.
