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.

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. [phone]) 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.

The EV CPS-2, two-channel power amplifier is recommended
for use with all FRi series loudspeakers, whether running
in passive or active crossover mode. This amplifier is
sufficient to operate up to two paralleled FRi series
cabinets per channel, supplying the necessary headroom
to provide appropriate long term program and instantaneous
peak power for most program materials. If array
configurations are designed as such to run in all passive
mode with more than two cabinets, an amplifier sufficient
to drive the total load requirements of the configuration
must be selected taking into consideration the individual
cabinet power requirements. For example, a 3 box array
containing two full range and one sub can be operated
in bi-amp mode with one channel of the CPS2 handling
the high frequency output of the crossover and feeding
the two full range cabinets and the other channel handling
the low frequency output of the crossover and feeding
the sub(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. Locate the seven-pin in-line connector, which will
be plugged onto the row of pins marked “PASSIVE”
on the circuit board.
4. Gently push the locking tab away from the
connector body and pull the connector body
straight off the pins.
5. Locate the row of pins immediately above marked
“BIAMP” and press connector body onto them.
6. Check to be sure all seven pins are engaged and
that the connector body is securely seated all the
way down in the receptacle.
7. Carefully re-install the assembly in the enclosure and
replace the mounting screws, making them snug
enough to compress the gasket for a secure air-tight
seal, but DO NOT OVER TIGHTEN!
8. Connect the high-frequency drive line to the upper
terminals (marked “INPUT BIAMP HF”) and the
low-frequency drive line to the lower set of terminals
(marked FULL RANGE/BIAMP LF).
9. Double-check for correct line assignment
and polarity on each input strip.

Typical FRi Input Panel
All FRi full range enclosures feature very high
quality barrier strip input terminations for ease
of installation and secure connections.
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. Should budget
allowances permit, limiters may prove a useful and an
appropriate addition to the signal path, especially for the
high frequency section. For more rudimentary clusters we
recommend the EV EX23 Active Crossover which contains
a 4th-order (24 dB/oct) Linkwitz-Riley and a stereo two-way
section with continuously variable crossover frequencies
from 80 - 8000 Hz. Each of the two outputs per channel
has separate mute switches and level controls. For
bi-amping the FRi Series in more complex array
configurations with delays and a greater need for
equalization, we recommend the EV Dx38 Digital Sound
System Controller, which incorporates all necessary
crossover, parametric EQ, shelving EQ, low- and high-
pass filters, alignment (delay), compressor and limiter
functions. (Settings for the Dx38 are available on the
EV Web site: www.electrovoice.com.)
Setting the
Electronic Crossover

• 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. Due to load
requisites some array configurations may not be
feasibly powered in all passive mode with typical
amplifiers available.
Recommended Configurations
for FRi Systems
Based on cost effectiveness of the entire system
(loudspeakers, processors, amplifiers), bi-amp
operation combines the overall best frequency
response and value. In simpler stereo applications
with one full range and one sub per side, we would
recommend a bi-amped mode of operation for
performance; however, all passive configurations
will typically supply adequate fidelity at an extremely
cost effective means. If multi-box arrays are used in
a stereo configuration, the recommendations for
mono program configurations apply to each side.
Cost Effective Fidelity
for the FRi System
To increase low frequency response, consider a
hard-surface coupled mounting surface of the sub(s).
These may be floors, walls or ceilings. Acoustically
coupling low-frequency cabinets to architectural
structures provide an extremely cost effective means
of providing more low-frequency energy in your system
without additional loudspeakers or electronics.

Rotatable Horn Information
All FRi-Series full-range speakers come with a high-
frequency, 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.
How to Rotate the Horns
Follow these six simple steps to rotate the horn:
1. Remove the grille assembly (as outlined in
Appendix B).
2. Stuff a clean, lint-free rag in the horn throat to
prevent debris and dropped screws from falling in
and possibly damaging the driver.
3. Remove the Philips head screws securing the horn
to the baffle.
4. Carefully lift the horn off the baffle, taking care
not to disturb the gasket, and rotate the horn
one-quarter turn.
5. Align the mounting holes and replace the screws.
Tighten the screws enough to compress the
gasket and provide a solid, air-tight seal, but
DO NOT OVER-TIGHTEN.
6. Carefully remove the rag and replace the
grille assembly.
