QRx118S
18” Subwoofer
Loudspeaker System
General 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 SPL1
@1 w/1 m (137 dB peak1) 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.
