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.

This perseverance has led to our pioneering new technologies that have

become industry standards: constant directivity horns, manifold technology,

Variable-D®microphones, hum-bucking coils for microphones, and the inclusion

of ultra-light weight neodymium in magnet structures (previously only utilized

by the auto industry) for microphones and loudspeakers, to name just a few.

It is our pleasure to provide you with the audio solution best suited for

your critical sound reinforcement needs. Congratulations on your

FRi-Series purchase!

To get the most out of your FRi-Series investment, please read carefully

through this entire FRi-Series guide. Inside you will find information that will

help you achieve maximum product life, optimum performance, and a safe,

successful installation.

FRi Series Overview

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.

In addition to the superior performance of the FRi Series,

flexibility, ease of suspension and array configuration all

merit the series suitable for most environments. The FRi

12-inch, 15-inch full range and 18-inch sub models all

measure 28 inches in the vertical dimension, allowing neat,

concise, and visually appealing arrays in either vertical or

horizontal arrays. The fully rotatable horn allows the

installer to construct the array to meet their coverage

needs while maintaining the most aesthetically pleasing

cabinet configuration. The structural integrity of all full

range FRi cabinets allow for vertical arrays up to a four

cabinet hang. In addition, the FRi-122/64 and FRi-

152/64 two-way speakers contain 12 suspension

points that enable a wide variety of flying configurations.

All are constructed in a trapezoidal design of 13 ply Baltic

Birch plywood with a detachable steel grille. The grilles

may be easily covered with acoustically transparent cloth.

The FRi-181S is supplied with 16 suspension points for

the ultimate in flexibility.

The FRi Series is specifically designed for use in stadiums,

houses of worship, live music clubs/discos, arenas and

gymnasiums. All systems employ EV’s exclusive Ring Mode

Decoupling (RMD™) and high-performance DL series

woofers to ensure maximum speech intelligibility and musical

clarity. Coupled with a fully rotatable high frequency horn,

all FRi models provide maximum flexibility.

Product Descriptions

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. The FRi-152/64 has a 15-

inch woofer and a 30-degree (15-degree angle per

side) trapezoidal enclosure. The loudspeaker can be oper-

ated in passive or bi-amp mode.

FRi-122/64

Similar in design, this two-way, direct-radiating loudspeaker

system features a 60 x 40-degree rotatable horn pattern,

which is ideal for far-field, long-throw applications.

The difference, however, is the FRi-122/64’s woofer size:

12 inches. As a result, the FRi-122/64 serves well as a

“stand alone” loudspeaker in small-to-medium sized

rooms requiring only moderate levels where mid-range

vocal intelligibility is important. The FRi-122/64 is contained

within a 30-degree (15-degree angle per side) trapezoidal

enclosure. The loudspeaker can be operated in passive

or bi-amp mode.

FRi-181S

A dedicated subwoofer loudspeaker system, the FRi-181S

functions efficiently in the lowest octave. It features an

18-inch woofer designed to provide huge amounts of

deep, full bodied, high-impact bass down to, and below,

the low open “E” on a bass guitar (approx. 41.7 Hz) with

little or no extra equalization required. The FRi-181S is

contained within a 15-degree (7.5-degree angle per side)

trapezoidal enclosure. This subwoofer can be operated in

passive or bi-amp mode.

Installation Environments

Interior 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.

The metal grille on the cabinets is designed to

accommodate custom-colored, acoustically transparent

fabrics which wrap neatly around the grille and is held in

place by U-channels (included). This allows the flexibility

to match most interior design requirements. We suggest

the use of acoustically transparent fabrics as supplied by

Stevenson & Lawyer (Tel. 1-800-968-5535) or equivalent

to ensure maximum performance and safety.

Outdoor Installation

Should your application call for outdoor installation,

locate the cabinet to provide protection from direct

exposure to sunlight, rain and other weather conditions.

Rigging

F R i

SPEAKER

SYSTEMS

Installation of the

Shoulder Eye Bolts

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:

1. Determine the intended location for the eyebolts on

the cabinet.

2. Remove and replace the 3/8-16 Phillips head screws

ONE AT A TIME. Replace screws with eye bolt, using

a washer (supplied) under each one.

3. Tighten each eye bolt “hand tight” and then torque

an additional 1/2to 3/4turn to accomplish

proper alignment.

WARNING: NEVER REMOVE MORE THAN ONE

3/8-16 PHILLIPS HEAD SCREW AT A TIME!

Removing two adjacent screws may cause the heavy

steel bracket to fall into the box, requiring disassembly of

the enclosure to put it back in place.

The FRi Series features internal heavy gauge steel

reinforcing brackets that are not only designed to provide

high safety factor support for the 3/8-16 forged eyebolt

rigging, but also to unitize the internal panels for each

enclosure. These corner braces are required to maintain

the structural integrity of the cabinet to performance levels

listed in this manual.

Basic Principles for Suspending

FRi Loudspeakers

Many “suspendible” loudspeaker designs offer “t-nut” style

mounting without using top and side enclosure panel

braces, thus producing lower safety factors. Therefore,

each FRi full range loudspeaker enclosure is furnished

with 12 fully supported mounting points to provide maximum

vertical or horizontal suspension. All systems have been

structurally certified to a minimum of 8 to 1 safety factor

loading. Each input panel provides safety information and

maximum safe multi-cabinet rigging data. Maximum safe

rigging configurations should never be exceeded.
