EAW products are continually improved. All specifications are therefore subject to change without notice. • PUB# MQ1364-888141 (A) /2 pp/4/15/99 • Printed In USA
DESCRIPTION
• Mid/High VA4 loudspeaker system
• Optimized for permanent installation only
• Horn-loaded 10-in cone with VA4 phase plug
• 2-in exit/75mm voice coil compression driver on
constant directivity horn
The new MQ Series represents the next generation of perma-
nent installation loudspeaker systems. Using VA4 Technol-
ogy developed for the new KF700 Series, the MQ range re-
places the MH and BV ranges of Virtual Array systems. The
Series comprises matched sets of mid/high and low frequency
enclosures that enjoy complementary dimensions and
trapeziod angles to facilitate the creation of optimized-cov-
erage arrays.
The MQ1364 uses a single, horn-loaded 10-in midrange cone
with a specially designed geometry that produces a time-
coherent wavefrontthroughtheupperportionof themidrange
that is critical to vocal articulation. A phase plug with radial
slots then serves to reduce the mechanical reactance of the
subsystem without affecting the directivity of the source,
allowing for flawless arraying of multiple MQ mid/high mod-
ules.
A high power 2-in exit/75mm voice coil high frequency com-
pression driver is mounted on a constant directivity horn for
consistent, accurate dispersal of HF information. The MQ1364
provides a nominal coverage pattern of 60°(h) x 40°(v).
APPLICATION
The MQ1364 mid/high module works with the MQ1312 triple
12-in low frequency module to create arrays for use in a
wide variety of permanently installed applications.
The most common array configuration is 2x MQ1364’s sepa-
rated by a single MQ1312. In such an array, a certain amount
of splay must be provided to achieve optimal coverage. Rig-
ging systems currently available allow users up to 10°of
overlap between the mid/high enclosures.
All MQ Series enclosures feature a comprehensive system of
3/8”-16 threaded mounting points for maximum flexibility
when suspending arrays overhead.
Applications include:
Large House of Worship
Arena
Stadium
Theater
Performing Arts Center

TECHNICAL SPECIFICATIONS MQ1364
DIMENSIONAL DRAWINGS ARCHITECTURAL SPECIFICATIONS
The two-way mid/high loudspeaker system shall incorporate
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 phase/
displacement plug. The HF driver shall be loaded on con-
stant directivity horn with a nominal coverage pattern of
60°(h) x 40°(v). An internal passive filter network shall
provide system equalization.
System frequency response shall vary no more than ±3 dB
from 190 Hz to 19 kHz measured on axis. The midrange fre-
quency section shall produce a Sound Pressure Level (SPL) of
109.5 dB SPL on axis at 1 meter with a power input of 1
Watt, and shall be capable of producing a peak output of
141.5 SPL on axis at 1 meter. The high frequency section
shall produce a Sound Pressure Level (SPL) of 114 dB SPL on
axis at 1 meter with a power input of 1 Watt, and shall be
capable of producing a peak output of 143 SPL on axis at 1
meter. The midrange frequency section shall handle 400 Watts
of amplifier power (AES Standard) and shall have a nominal
impedance of8 Ohms.Thehigh frequency sectionshallhandle
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 black catalyzed poly-
urethane. Input connectors shall be 4-terminal barrier strip
and one Neutrik NL4 Speakon. A total of sixteen 3/8"-16
threaded mounting/suspension 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 two-way mid/high loudspeaker shall be the EAW model
MQ1364.
