18-inch low-frequency system l Extends FRi bass to 36 Hz l Built-in Low-pass filter -- may be traditionally biamped or simply connected in parallel with full-range systems | Vented slot load design | Trapezoidal (7.5° per side) | Comes with 4 eyebolts | 16 x 3/8”-16 suspension points.
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.
