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 sub­woofer, full-range systems with easily switchable passive or bi­amp 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.
