Manufacturer description

Two Differential Drive woofers and a large double-flared port extend bass right down to 25 Hz with low turbulence, and the enclosure can be run in omnidirectional or cardioid configurations to keep energy off the stage. Spring-loaded two-point rigging allows flown columns of up to 16 boxes, while M20 pole sockets on top suit ground stacking with compatible VTX tops. Powered by Crown I-Tech HD amplification, it integrates seamlessly with every VTX full-range model.
