MB 156/3

Art. No. 5925

Construction

At first the 80° bevel has to be added to all adequate boarders and sides of the cabinet panels which 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 tapering cabinet design is just for aesthetics. The cabinet can also be built in oblong design when the volume is retained.

The crossover has to be mounted on the inner side of the rear panel across from the woofer.

Inner damping

The damping material is loosely pushed into the cabinet. The space immediately behind the bass reflex cut outs must remain free.
