TECHNICAL SPECIFICATIONS MQ1366

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 matched sets o f mid/high and low fr equency
enclosures that enjoy complementary dimensions and
trapeziod angles to f acilitate the creati on of optimized-cov­erage arrays.

The MQ1366 uses a single , horn-loaded 10-in mi dran ge con e
with a specially designed geometry that produces a time­coherent wavefr ont through the upper portion o f the midran ge
that is critical to vocal articulation. A phase plug with r adial
slots then serves to redu ce the mechanical reactan ce 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. Th e MQ1366
provides a nominal coverage pattern of 60° (h) x 60° (v).

APPLICATION

The MQ1366 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 MQ1366’s sepa­rated by a single MQ1312. In such an arr ay , a certain amount
of splay must be provi ded to achi eve optim al coverag e . 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

ARCHITECTURAL SPECIFICATIONS

The two-way mid/high lou dspeaker system shall incorpor ate
a 10-in cone MF transd ucer 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 high d en 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
60° (h) x 60° (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 midr ange fre­quency section shall prod uce a Sound Pressur e Level (SPL) of

109.5 dB SPL on axis at 1 meter with a power input of 1
Watt, and shall be capable of producing a peak output of

141.5 SPL on axis at 1 meter. The high frequency section
shall produce a Soun d Pressure Level (SPL) o f 112 dB SPL on
axis at 1 meter with a power input of 1 Watt, and shall be
capable of producing a peak output of 141 SPL on axis at 1
meter . The midr ange frequen cy section shall handle 400 W atts
of amplifier power (AES Stand ard) and shall have a nominal
impedance of 8 Ohm s. The high frequen cy section shall handle
200 Watts of amplifi er power (AES Stan dard) and shall have
a nominal impedance of 8 Ohms.

The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of 15mm thi ckness void-free cr oss-grain­laminated Baltic birch plywood and shall employ extensive
internal bracin g. It shall be finished in black catalyzed poly­urethane. Input connectors shall be 4-terminal barrier strip
