All the cabinet panels are cut from 19 mm chipboard or medium density fibreboard, butt-jointed and glued. After that, the openings for the driver and terminals are cut out and any necessary recesses cut. The chamfer on the outer baffle can be made either before the cabinet is glued together or afterwards.
The crossover has to be mounted on the inner side of the rear panel across from the woofer.
The damping material is loosely pushed into the cabinet. The space immediately behind/above the bass reflex tunnel must remain free.
