The cut sections of the cabinet, except for the base, are glued as shown in the drawing. Bevels can be cut with an adjustable jigsaw or circular saw. Since it is not always easy to set the exact angle, it is worth making a couple of trial cuts on spare wood.
The cabinet is made with a double floor to enable the crossover to be positioned outside the speaker housing chamber itself. The base to which the crossover is attached is then screwed to the cabinet from below. The pre-drilled cable holes inside the housing must be filled afterwards using hot-melt glue or silicon mastic.
Half a mat of damping material is placed inside the mid-range housing while 2 mats each are placed inside the woofer spaces. The space behind the bass reflex tubes should remain free.
