15-Inch Two-Way
Horn-Loaded 60° x 60°
Coaxial Speaker System
General Description:
FRX+ series is designed for applications in highly
reverberant spaces where excellent directivity control down
to 500 Hz is critical. In a trapezoidal enclosure no taller
than a typical compact system and only a bit wider, they
maintain control of coverage angles down to 500 Hz. A 15"
LF transducer is coaxially horn loaded with a mouth nearly
the size of the enclosure to provide excellent LF pattern
control. These professional fixed install speakers deliver a
broad range of performance options including multiple
rotatable horn patterns, matching sub-woofer, easily
switchable passive or bi-amp operation, and EV’s world
renowned transducer technology for response that is smooth
and linear. The FRX+ is an economical and flexible solution
for the most demanding installations.
Same size full-range and sub-woofer systems allow the
installer to construct arrays covering the most demanding
acoustical environments while maintaining an aesthetic
and uniform installation. The structural integrity of the
FRX+ cabinets allows for vertical arrays up to 2 boxes in
height. All FRX+ systems are available in black or white
EVCoat
stainless steel hardware and a multilayer stainless steel
grille that protects against rain, sprayed water, and dust
to IEC 529 IP 44 Mil Spec 810 humidity, salt spray, and UV
specifications. External components and fasteners are
aluminum and stainless steel. Performance may be
further enhanced by bi-amping with the Electro-Voice Dx38 Digital Sound System Processor. A 300W line
transformer is available as a contractor installed item.

Architectural & Engineering Specs:
The loudspeaker system shall be a coaxial, two-way full range design consisting of a 15-inch woofer, a high-frequency compression
driver on a molded constant-directivity horn and a dividing network providing an acoustic crossover frequency of 1,350 Hz. The
system shall be configurable in a biamp mode by moving a single connector in the crossover network. The loudspeaker shall meet
the following performance criteria; power-handling, 400 watts, based upon ANSI/EIA RS-426-A 1980 standard for full-range loudspeaker
systems; frequency response, smooth and usable at high SPL levels from 60 Hz to 15 kHz; pressure sensitivity, 104 dB SPL
(passive mode) or 105 dB (LF)/109 dB (HF) in biamp mode for 1W at 1m; impedance, 8 ohms nominal, 7 ohms minimum. The
system shall have a distribution pattern of 60° nominal horizontally from 500 Hz to 15 kHz and 60° nominal vertically from 500
Hz to 15 kHz. The enclosure shall be constructed from 13-ply birch plywood and braced appropriately, and the grille shall be
constructed from 16GA powder-coated steel backed by acoustically transparent fabric. The PI version shall have multilayer
stainless steel grille, stainless steel fasteners, and aluminum hardware. The dimensions shall be 800 mm (31.5 in.) high by
724 mm (28.5 in.) wide by 686 mm (27.0 in.) deep. Net weight shall be 68.95 kg (152 lb).
The two-way loudspeaker shall be the Electro-Voice FRX+660 or FRX+660PI.
