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.
