TECHNICAL SPECIFICATIONS MQ1394
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 r epresen ts the n ext g ener ation o f perm anent installation loudspeaker systems. Using VA4 Technology developed for the new KF700 Series, the MQ range replaces the MH and BV ranges of Virtual Array systems. The
Series comprises match ed sets of mid/high and low fr equency
enclosures that enjoy complementary dimensions and
trapeziod angles to facilitate the creation of optimizedcoverage arrays.
The MQ1394 uses a horn-loaded 10-in mi dran g e con e with a
specially designed geometry that produces a time-coherent
wavefront through the upper porti on of the mi dr ange 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
modules.
A high power 2-in exit/75mm voice coil hi gh frequency compression driver is m ounted on a constan t directivity horn f or
consistent, accurate dispersal o f HF information. The MQ1394
provides a nominal coverage pattern of 90° (h) x 40° (v).
APPLICATION
The MQ1394 mid/high m odule 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 separated by a single MQ1312. Unlik e most oth er 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, fanshaped 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 lou dspeaker system shall incorpor ate
a 10-in cone MF tran sducer and a 2-in exit compressi on driver
HF transducer.
The MF driver shall be loaded into a midrange horn constructed of 3mm birch plywood r einfor ced with hi gh den sity
polyurethane foam. The MF horn shall incorporate a phase/
displacement plug. The HF driver shall be loaded on constant directivity horn with a nominal coverage pattern of
