Description

The QRx-118S is a dedicated 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.
