TECHNICAL SPECIFICATIONS MQ1364

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 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 f acilitate the cr eation of optimized-cov­erage arrays.

The MQ1364 uses a single, h orn-loaded 10-in mi dr ange cone
with a specially designed geometry that produces a time­coherent wavefr ont through the upper portion of th e midran ge
that is critical to vocal articulation. A phase plug with r adial
slots then serves to reduce the mechanical reactance of the
subsystem without affecting the directivity of the source,
allowing for flawless arrayin g of multiple MQ mi d/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 MQ1364
provides a nominal coverage pattern of 60° (h) x 40° (v).

APPLICATION

The MQ1364 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 MQ1364’s sepa­rated by a single MQ1312. In such an arr ay, a certain am ount
of splay must be provi d ed to achieve optim al cover age . Ri g­ging 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
