Fostex BK-12m – 4.5” Full-Range Folded Horn Cabinet - Each

This is the flat-pack cabinet used in the Fostex BK-12m Speaker Kit.

The cabinets are locally cut by CNC machine from high quality multi-layer 11/16” Baltic Birch and delivered flat packed.

The through hole for the driver measures 4.05" (103mm) and is chamfered to promote optimal air flow. While this cabinet was designed for use with the FE126En, the FE108-SOLFF125WK and discontinued FE126E, FE127E, and FF125K will also fit. You can use alternate full range drivers of your choice in this cabinet as well. The maximum driver depth the cabinet will accommodate is 3.54" (90mm). 

Wood glue, clamps and a little sand paper are all that is required for assembly. Detailed assembly instructions are also included.

Completed cabinets measure 31 5/8” tall x 7 1/4” wide x 14 1/2” deep. The unfinished/unstained wood is ready for your choice of finish. You may also choose to round over the edges if you prefer that style of appearance.

The rear of the cabinet is already cut with two holes for binding posts. We recommend the Propeller Posts. Please select your preference from the drop down menu. You may also choose to cut a hole for an input cup if you prefer a flush rear of the cabinet as opposed to binding posts.

Tools Required for Assembly:

  • Elmer’s Wood Glue
  • Sand Paper
  • Bar Clamps (3x 24", 2x 36" - the more the better. Available at your local hardware store, or online at
