The Electro-Voice QRx-118S is a dedicated PA subwoofer loudspeaker system that incorporates the EVX-180B 4-inch voice coil driver for maximum LF reproduction power with minimum box volume.

This vented, 600-watt system easily provides 131 dB SPL at 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-inch 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.
