Welcome to Speaker Builder

Welcome to Speaker Builder - your source in the UK for CNC made flatpack kits and cabinets for bass and guitar speaker cabinets.


Due to continued problems with relocating the workshop, we cannot currently take any orders.

Flatpack Kits
We offer a growing range of precisely made flatpack "kits" for constructing bass and guitar cabinets - allowing you to easily assemble a superb quality cabinet and finish it to your own preferences. We can also offer cabinet hardware, wadding, tolex and other bits to help you complete your project.

Completed Cabinets

We can supply cabinets in different levels of completion - from bare ply with all edges rounded and ready for finishing, right through to a completely finished cabinet including crossover, speakers and all hardware, fitted and tested - all you have to do is plug in! You will find options for build level against each of the flatpack kits - contact us for prices for sompleted cabinets.

All cabinets and kits are offered using high quality baltic birch or an ultra lightweight ply.

To launch our range, we are starting off with the highly regarded fEARful bass cabinets - we are the UK authorised builder of these superb cabinets.
