TECHNICAL SPECIFICATIONS MQV1364
DESCRIPTION
The MQV Series is part of the next generation of permanent
installation loudspeakers. Using VA4 Technology developed
for the KF700 series, the MQV range replaces the ASV range
of virtual array systems.
The MQV1364 uses a single, direct radiating 15-inch woofer
in an optimally vented enclosure.
A single, horn loaded 10-inch midrange cone with a special
geometry is used which produces a time coherent wavefront
through the upper portion of the midrange that is critical to
vocal articulation. A phase plug with radial slots then serves
to reduce the mechanical resistance of the subsystem with-
out affecting the directivity of the source, allowing flawless
vertical arraying of multiple MQV modules
A high power 2 inch exit/75mm voice coil compression driver
is mounted on a constant directivity horn for consistent,
accurate dispersal of HF information.
APPLICATIONS
The MQV1364 is engineered as a full range component for
very large format arrays and is an effective tool in large-
scale permanent installations. Comprehensive mounting
points allow for flexible installation.
Applications include:
Large Church Large Arenas
Stadiums

DIMENSIONAL DRAWING ARCHITECTURAL SPECIFICATIONS
The three-way full range loudspeaker system shall incorpo-
rate a 15-in woofer (vented), a 10-in cone MF transducer,
and a 2-in exit compression driver HF transducer.
The MF driver shall be loaded into a midrange horn con-
structed of 3mm birch plywood reinforced with high density
polyurethane foam. The MF horn shall incorporate a radial
phase plug. The HF driver shall be loaded on constant direc-
tivity horn with a nominal coverage pattern of 60° (h) x 45°
(v).
System frequency response shall vary no more than ±3 dB
from 50 Hz to 16 kHz measured on axis. The midrange fre-
quency section shall produce a Sound Pressure Level (SPL) of
109 dB SPL on axis at 1 meter with a power input of 1 Watt,
and shall be capable of producing a peak output of 141 SPL
on axis at 1 meter. The high frequency section shall produce
a Sound Pressure Level (SPL) of 113 dB SPL on axis at 1
meter with a power input of 1 Watt, and shall be capable of
producing a peak output of 142 SPL on axis at 1 meter. The
midrange frequency section shall handle 400 Watts of ampli-
fier power (AES Standard) and shall have a nominal imped-
ance of 8 Ohms. The high frequency section shall handle 200
Watts of amplifier power (AES Standard) and shall have a
nominal impedance of 8 Ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of 15mm thickness void-free cross-grain-
laminated Baltic birch plywood and shall employ extensive
internal bracing. It shall be finished in wear-resistant tex-
tured black paint. Input connectors shall be 1x 6-terminal
barrier strip and one Neutrik NL8 Speakon. A total of sixteen
3/8"-16 threaded mounting points (4 each top, bottom and
sides) shall be provided. The front of the loudspeaker shall
be covered with a powder coated perforated steel grill.
The three-way full range loudspeaker shall be the EAW model
MQV1364.
