General Description:

The FRi+181 is designed for applications where extended low

frequency response is desired in an FRi/FRi+ installation. It is

a trapezoidal enclosure identical in height, appearance and

suspension to the FRi/FRi+ 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 FRi/

FRi+ Series is an economical and flexible solution for the

most demanding installations.

Same height 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 FRi/FRi+

cabinets allows for vertical arrays up to 2 boxes in height. All

FRi/FRi+ systems are available in weather resistant black

Futura, white, and unfinished. Performance my be further

enhanced by bi-amping or tri-amping with the Electro-Voice

Dx-38 Digital Sound System Processor.
