Almighty Subwoofers, Part 2: Enclosure Details

Enclosure details
All parts maked grey on the 3D image of the cabinet are 'sandwiches' made of 3 layers of 12 mm HDF, the middle filled with sand. The easiest way to do this is to use three equally sized boards, and make a large cut-out in the middle board. I made a square cut-out leaving a 70 mm wide rim. The open space inside should be supported by spacers to avoid warping Fig. 1. Inside the sandwich. All other boards are 19 mm HDF.
The vertical braces inside the enclosure are one piece, the horizontals are three separate pieces. The spacers inside the port runs all the way back to the rear wall (this is hidden on the 3D image), and so do the braces. The front baffle consists of two layers of 19 mm HDF.
The cut-outs are 390 mm for the inner baffle and 355 mm for the outer baffle.
