FRX+181
Vented Direct Radiating
18 inch Subwoofer
Speaker System
General Description:
The FRX+181 is designed for applications where extended
low frequency response is desired in an FRX+ installation. It is
a trapezoidal enclosure identical in size, appearance and
rigging to the FRX+ full-range systems. An 18" LF transducer
is centrally mounted in a large optimally-vented enclosure for
efficient deep-bass response that requires only minimal
equalization. These professional fixed install speakers
deliver a broad range of performance options including
multiple rotatable horn patterns, matching sub-woofer, full-
range systems with easily switchable passive or bi-amp
operation, and EV’s world renowned transducer technology for
response that is smooth and linear. The FRX+ Series is an
economical and flexible solution for the most demanding
installations.
Same size full-range and sub-woofer systems allow the
installer to construct arrays covering the most demanding
acoustical environments while maintaining an aesthetic and
uniform installation. The structural integrity of the FRX+
cabinets allows for vertical arrays up to 2 boxes in depth. All
FRX+ systems are available in weather resistant black or
white EVCoatTM, and unfinished. A severe environment
weatherization option is also available. Performance my be
further enhanced by bi-amping or tri-amping with the Electro-
Voice Dx-38 Digital Sound System Processor.
