Downloads
The QRx-118S is a dedicated subwoofer loudspeaker system that incorporates the EVX-180B 4" voice coil driver for maximum LF reproduction power with minimum box volume. This vented, 600-watt system easily provides 131 dB SPL @1 w/1 m (137 dB peak) at full power in a rectangular enclosure that is stable and readily stacks for extra energy or slides easily under even the lowest stages.
The QRx-118S cabinet has recessed side safety handles for ease of transport and includes 1-3/8" pole mount receptacle for use with full range cabinets without the need for extra mounting stands. The rear of the cabinet includes four 1/4-20 threaded T-nuts for affixing casters or dollies. Enclosure is built from 13-ply, void-free, grain-oriented birch plywood finished with Futura™, a sprayed-on polyurethane finish that is very rugged. Available in black or white finishes.
