Assembly
Simply glue the boards together (butt-jointed). The chamfers on the baffle can 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 terminal in the rear wall.
Depending on how the amplifier module is built, it may be necessary to physically separate the loudspeaker space from the amplifier module. In this case, the cabinet will have to be made larger so as not to steal any space from the woofer enclosure.
Inner damping
The damping material is evenly distributed in the cabinet.
