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 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).

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.
