FEATURES
• Compact Virtual Array Technology™ three-way system
• Horn-loaded MF/HF (60°x 45°coverage pattern)
• 15-in LF/8-in MF/1.4-in exit HF
• Switchable powering: full range passive or bi-amp
(passive LF/MF)
• For portable use or permanent installation
DESCRIPTION
A 3-way full range system in a trapezoidal enclosure.
Includes a 15-in woofer, a horn-loaded 8-in midrange cone
and a 1.4-in exit/1.75-in voice coil compression driver on a
60°x 45°constant directivity horn. The powering mode is
switchable: passive (3-way crossover) or bi-amplified (pas-
sive low/mid crossover).
APPLICATIONS
The LA460 applies Virtual Array Technology to small venue
performance in both portable applications and permanent
installations. With EAW’s mathematically correct midrange
flare, pattern control is maximized throughout the vocal
region providing exceptional speech intelligibility in a
compact enclosure. Six year warranty.
Applications include:
Band PA Dance Clubs Portable A/V

DIMENSIONAL DRAWING A & E SPECIFICATIONS
The three-way full range loudspeaker systems shall incorpo-
rate a 15-in LF transducer, an 8-in MF transducer and a 1.4-
in exit/1.75-in voice coil compression driver HF transducer.
The LF driver shall be mounted in a vented enclosure tuned
for optimum low frequency response. The MF driver shall be
loaded into a midrange horn constructed of 1/8-in birch ply-
wood reinforced with high density polyurethane foam. The
MF horn shall incorporate a phase/displacement plug. The
HF driver shall be loaded on a constant directivity horn with
a nominal coverage pattern of 60°(h) x 45°(v).
Powering mode shall be switchable between full range pas-
sive and bi-amplified operation. In full range passive mode,
an internal passive filter network shall provide fourth order
acoustical crossover and system equalization between the
low, mid and high frequency sections. In bi-amplified mode,
an internal passive filter network shall provide fourth order
acoustical crossover and system equalization between the
low and mid frequency sections.
System frequency response shall vary no more than ±3 dB
from 62 Hz to 20 kHz measured on axis. The full range sys-
tem shall produce a Sound Pressure Level (SPL) of 97 dB SPL
on axis at 1 meter with a power input of 1 Watt and shall be
capable of producing a peak output of 130 dB SPL on axis at
1 meter. The low/mid section in bi-amplified mode shall pro-
duce a Sound Pressure Level (SPL) of 97 dB SPL on axis at 1
meter with a power input of 1 Watt, and shall be capable of
producing a peak output of 130 dB SPL on axis at 1 meter.
The high frequency section in biamplified mode shall pro-
duce a Sound Pressure Level (SPL) of 108 dB SPL on axis at
1 meter with a power input of 1 Watt, and shall be capable
of producing a peak output of 136 dB SPL on axis at 1 meter.
The full range system shall handle 500 Watts of amplifier
power (AES Standard) and shall have a nominal impedance
of 8 Ohms. The low/mid section in biamplified mode shall
handle 500 Watts of amplifier power (AES Standard) and shall
have a nominal impedance of 8 Ohms. The high frequency
section in biamplified mode shall handle 150 Watts of am-
plifier power and shall have a nominal impedance of 8 Ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of 1/2-in thickness void-free cross-grain-
laminated Baltic birch plywood and shall employ extensive
internal bracing. It shall be finished in black catalyzed poly-
urethane. Input connectors shall be 2x Neutrik NL4 Speakon.
A total of 3x 3-position flytracks with integral 3/8"-16
threaded mounting points (2 top and 1 back) shall be pro-
vided. The front of the loudspeaker shall be covered with an
arced, vinyl-coated, perforated steel grille.
The 3-way full range loudspeaker shall be the EAW model
LA460.
