NoBox BB

Art. No. 5989

Construction

The panels are cut to size and glued together as shown in the drawing. The crossover can be attached to the rear of the baffle between the loudspeakers, for example, or on the base. The terminal connections are fitted to the vertical panel attached to the base.

Proposal 2 is more complicated. The edges are embellished with solid wood strips. In addition, a grille frame is included so that the entire front can be covered with fabric (please order separately). The frame is simply forced between the side pieces. The woofer should be recessed by 10 mm so that it does not touch the fabric.

If critical tube amplifiers are used, the impedance curve should be made more linear (see circuit diagram). The components are mounted on a separate PCB as shown in the circuit diagram and connected upstream of the input to the NoBox BB crossover.
