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 FRi152/64 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 15inch woofer and a 30-degree (15-degree angle per
side) trapezoidal enclosure. The loudspeaker can be operated 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.

FRi-152/64
The two-way full range loudspeaker system shall incorporate
a 15-in. LF transducer and a 2-in./50mm voice coil HF
compression driver.
The LF driver shall be mounted in a vented enclosure tuned
to optimum low-frequency response. The HF driver shall
be loaded on a constant-directivity horn with a nominal
coverage pattern of 60 x 40-degrees. An internal passive
filter network shall provide for component crossover and
system equalization. Input panel shall be easily changeable

producing a full-power long-term average output of 123 dB
on axis at 1 meter. It shall handle 350 watts of amplifier
power long-term (EIA Standard) and shall have a nominal
impedance of 8 ohms.
The loudspeaker enclosure shall be trapezoidal in shape
with side draft angles of 15 degrees each. It shall
