Simply glue the boards together (butt-jointed). The chamfers on the bafflecan be applied with a power jig or circular saw set to 45° or applied later using an orbital sander.
Next, cut out the openings for the drivers and the bass reflex tube. If an amplifier module is to be used, the cut-out required for fitting it is cut into the rear wall. If no amplifier unit is to be used, fit the ST 77 connection terminals in the rear wall.
Distribute the 4 mats of damping material uniformly throughout the cabinet.
