The NoBox BB unites a number of preferences in a single concept: it achieves the directness of a full-range loudspeaker, in particular in the voice range, and also manages to produce powerful, stable bass without having to fill the room with hardware.

The B 200 6 Ohm is used in the NoBox BB together with a 38 cm BGS 40 8 Ohm woofer in an open baffle as a dipole. The electric separation between the two drivers is low enough (250 Hz), which enables the full-range speaker to make full use of its capabilities and the BGS 40 8 Ohm is effectively the supporting woofer. The BGS 40 8 Ohm is a musician's driver with high sensitivity and can, as a result, easily be adapted to the B 200 6 Ohm without giving anything away in terms of mean sound pressure.

Despite the baffle being open, which theoretically causes an acoustic short circuit in the bass range, the system produces a dynamic low bass output down to 32 Hz (-10 dB). One reason for this is that the baffle is cut off from the floor and so no acoustic short circuit can take place in this direction. In addition, the side panels of the cabinet, which are mainly for stability, increase the acoustic distance travelled

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.
