New style High Power 18" Subwoofer for Event


VRS33 is a unique design, with an 18 inch subwoofer at the front and a 15 inch subwoofer at the back. Dual-channel control gives a forward directied bass radiation with a damping of up to 15 dB in the rear.This results in a much more solid, tight and musical bass sound, especially in environments with difficult acoustics. Also actors on the stage and neighbours behind the venue are beeing spared from too much low frequency energy.


Many different stacking variants are available with the VRS33. With the same system width and the same rigging gear, the VRS33 can be integrated inconspicuously into a VR36 array. But also classic L-R-stacks, horizontal rows in front of the stage and complete vertical bass arrays are possible. Either stacked or flown.
