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 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
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
