EAW MQ1394 is a mid/high VA4 loudspeaker system comprised of a horn-loaded 10-in cone and a 2-in exit/75mm voice coil compression driver. It's designed for permanent installation and optimized for clear vocal delivery with a time-coherent wavefront and a phase plug that reduces mechanical reactance. The MQ1394 provides a nominal coverage pattern of 90° (h) x 40° (v) and is suitable for use in a wide range of venues, including Houses of Worship, arenas, theaters, performing arts centers, and stadiums.

EAW products are continually improved. All specifications are therefore subject to change without notice. • PUB# MQ1394-888143/2 pp/4/15/99 • Printed In USA
DESCRIPTION
• Mid/High VA4 loudspeaker system
• Optimized for permanent installation only
• Horn-loaded 10-in cones 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-
coverage arrays.
The MQ1394 uses a horn-loaded 10-in midrange cone with a
specially designed geometry that 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 reactance of the sub-
system without affecting the directivity of the source, al-
lowing for flawless arraying of multiple MQ mid/high
modules.
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 MQ1394
provides a nominal coverage pattern of 90° (h) x 40° (v).
APPLICATION
The MQ1394 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 MQ1394’s sepa-
rated by a single MQ1312. Unlike most other 90° horizontal
coverage array modules, the MQ1394 is designed to tight
pack with the MQ1312 to achieve optimal coverage. This
provides an excellent center channel array for large, fan-
shaped venues that use an L/C/R configuration.
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

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
90° (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
108.5 dB SPL on axis at 1 meter with a power input of 1
Watt, and shall be capable of producing a peak output of
140.5 dB SPL on axis at 1 meter. The high frequency section
shall produce a Sound Pressure Level (SPL) of 110.5 dB SPL
on axis at 1 meter with a power input of 1 Watt, and shall be
capable of producing a peak output of 139.5 dB 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 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 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
MQ1394.

EAW MQ1394 is a mid/high VA4 loudspeaker system comprised of a horn-loaded 10-in cone and a 2-in exit/75mm voice coil compression driver. It's designed for permanent installation and optimized for clear vocal delivery with a time-coherent wavefront and a phase plug that reduces mechanical reactance. The MQ1394 provides a nominal coverage pattern of 90° (h) x 40° (v) and is suitable for use in a wide range of venues, including Houses of Worship, arenas, theaters, performing arts centers, and stadiums.
