QCB 318

The QCB 318 is a directional radiating 3 x 18" bass speaker system. The digital controller amplifier DA 230 (with preset) enables a cardioid dispersion with a front-to-back damping of more than 20 dB in a wide frequency range. The subwoofer system can be used in bigger production surroundings (open airs, big indoor events and installations).  The construction features of the PANO product family are also taken over to this system. The black polyurethane coated birch plywood casing is equipped with 8 ergonomical set handles and four 100 mm blue wheels. Stacking elements and multiply bolted foot elements made out of special plastics provide a safe grip when stacked.
