Fostex BK-20 Cabinet - Sold Flat - Each

Folded Horn BK-20 Baltic Birch Cabinet - Pre-cut Wood for 8" Full Range Speaker

The wood pieces for the BK20 are all pre-cut and sold flat. The side walls have been grooved to make positioning and assembly easier. The Baltic Birch is 3/4" thick and doubled up for the front baffle per the Fostex cabinet plans.

The driver hole has been cut to 182mm to accept most Fostex 8" full range speakers. The rear of the driver hole has been well chamfered to allow for optimal air flow.

We recommend the Fostex FE206En full range speaker, but the cabinet will also work for the FE208E Sigma, FE207E (no longer available), and FF225K (no longer available).

Please look at the BK-16 and BK-12m kits as an example of what this will look like finished.

You may also decide to add a super tweeter to your speaker. The Fostex T90A would be a good choice, it works very well in the BK-16 kit.

The rear panel is pre-cut for a perfect flush mount of the TD-CUP dual binding post input cup. This allows for the easy addition of a super tweeter.  Don't foget to order these with your cabinets.

After assembly, you may wish to round off the corners and then stain, clear coat, or paint the cabinet.
