F R i S P E A K E R S Y S T E M S Welcome Dear Sound Professional: Thank you for choosing EV products. For more than 70 years, we have persevered to design, engineer, and manufacture the most innovative and highest quality audio products for indoor and outdoor spaces, including offices, houses of worship, live music venues, auditoriums and stadiums.
FRi Series Overview F R i S P E A K E R S Y S T E M S Contents FRi Series Overview Page The Electro-Voice FRi-Series of fixed installation, sound reinforcement loudspeakers deliver a broad range of performance options to accommodate the acoustic requirements of most environments. All full range FRi models employ EV’s renowned DH2t two-inch diaphragm compression driver to deliver sound reproduction that is smooth and linear.
FRi Series Overview F R i S P E A K E R S Y S T E M S Product Descriptions Architects’ and Engineers’ Specifications FRi-152/64 FRi-152/64 The FRi-152/64 features a 60 x 40-degree rotatable horn pattern, which is ideal for far-field, long-throw applications. The FRi-152/64 serves well as a “stand alone” loudspeaker in small-to-medium sized rooms requiring only moderate levels but good bass response as a two-way, direct-radiating loudspeaker system as well.
FRi Series Overview F R i S P E A K E R S Y S T E M S FRi-122/64 FRi-181S The two-way full range loudspeaker system shall incorporate a 12-in. LF transducer and a 2-in./50mm voice coil HF compression driver. The subwoofer loudspeaker system shall incorporate one passive or biampable 18-in. LF transducer mounted in a vented, slot-loaded enclosure tuned at optimum low frequency response. The LF driver shall be mounted in a vented enclosure tuned to optimum low-frequency response.
FRi Series Warranty F R i S P E A K E R S Y S T E M S Uniform Limited Warranty Electro-Voice products are guaranteed against malfunction due to defects in materials or workmanship for a specified period, as noted in the individual product-line statement(s) below, or in the individual product data sheet or owner’s manual, beginning with the date of original purchase. If such malfunction occurs during the specified period, the product will be repaired or replaced (at our discretion) without charge.
Installation Environments F R i S P E A K E R S Y S T E M S Interior Installation Outdoor Installation The standard FRi cabinets are constructed for indoor installation to provide years of trouble-free service. The paint on the cabinets is textured and highly durable. Should you endeavor to paint your cabinet another color, clean and prep the cabinet as you would following standard painting practices.
Rigging F R i S P E A K E R S Y S T E M S Installation of the Shoulder Eye Bolts Basic Principles for Suspending FRi Loudspeakers Rigging of the FRi-Series is done with readily available 3/8-16 forged shoulder eye bolts. To install the eye bolts, follow these steps: Many “suspendible” loudspeaker designs offer “t-nut” style mounting without using top and side enclosure panel braces, thus producing lower safety factors.
Rigging F R i S P E A K E R S Y S T E M S Rigging to the 3/8 Forged Eyebolts Recommended rigging to the 3/8 forged eyebolts (4 supplied) with each system is as follows and is dependent upon following all recommended loading requirements for safety.

Rigging Amplifier Recommendations F R i S P E A K E R S Y S T E M S Rigging Options Amplifier Recommendations EV has coordinated with ATM Flyware and Polar Focus in developing pre-designed flying hardware to support the most common array configurations of one sub flanked by two full-range loudspeakers. To receive additional information, please contact either of these fine companies.
Biamp Operation Biamp Operation F R i S P E A K E R S Y S T E M S Changing the “BIAMP Mode” All FRi-Series units are shipped from the factory in “PASSIVE” mode operation. To change to the “BIAMP” mode, follow these steps: 1. Remove the screws holding the input terminal cup to the cabinet. 2. Carefully remove the assembly far enough to get a good look at the back of the circuit board (about six to eight inches). 3.
Electronic Crossover F R i S P E A K E R S Y S T E M S Setting the Electronic Crossover The active crossover centerpoint is 1600 Hz with a crossover type of 4th-order (24 dB/oct) Linkwitz-Riley, recommended. The full range active crossover should be set for 1600 Hz; however, if adjustments are made or variations are implemented do not use frequencies below 1480 Hz! Crossover slope should be 24 dB/octave.
Basic Configurations F R i S P E A K E R S Y S T E M S Recommended Configurations for FRi Systems • Bi-amp Operation BEST • All Passive Operation BETTER • Tri-amp Operation NOT RECOMMENDED Due to the inherent designs and efficiencies of the FRi systems, there is no cost effective reason to utilize all active operation in either mono or stereo mode. Actual cost of electronics and amplification will be determined by the total number of FRi cabinets configured within the array.

Appendix A: Mechanical Adjustments F R i S P E A K E R 40º S Y S T E M S Rotatable Horn Information All FRi-Series full-range speakers come with a highfrequency, constant-directivity horn that is fully rotatable. Depending on the model, the horn may be rotated up to 90 degrees to maintain the speaker’s same horizontal coverage angle with the cabinet on its side. This is especially useful in low-ceilinged rooms and in the construction of vertical line source arrays.
