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.

Specifications
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
from passive to biamp operation via internal connector.
System frequency response shall be 70 Hz to 15 kHz
(-3 dB) measured on axis. The loudspeaker shall produce
a sound pressure level (SPL) of 98 dB on axis at 1 meter
with a power input of 1 watt, and shall be capable of
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
be constructed of 13 ply void-free cross-grain-laminated
Birch plywood and shall employ extensive wooden bracing.
It shall be finished in black or white acrylic paint or
available unfinished. Input connectors shall be two
2-terminal barrier strips. A total of twelve 3/8-16 threaded
mounting/suspension points shall be provided, (three
each on top and bottom, two per side, two on rear).
The front of the loudspeaker shall have a powder-coated
perforated 16 GA steel grille. Grille mounting shall allow
for acoustically transparent fabric to be applied without any
noticeable protrusions or fasteners.
The two-way full range loudspeaker shall be the
Electro-Voice model FRi-152/64.
