TECHNICAL SPECIFICATIONS MQV1366

FEATURES

•Full Range VA4™ loudspeaker system

•Optimized for permanent install only

•Direct radiating 15-inch woofer in optimally vented
enclosure

•Horn loaded 10-inch cone with VA4™ phase plug

•2-inch exit/75mm voice coil compression driver on
constant directivity horn

DESCRIPTION

The MQV Series is part of the next generation of permanent
installation loudspeakers. Using VA4™ Technology developed
for the KF700 series, the MQV range replaces the ASV range
of virtual array systems.

The MQV1366 uses a single, direct radiating 15-inch woofer
in an optimally vented enclosure.

A single, horn loaded 10-inch midrange cone with a special
geometry is used which 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 resistance of the subsystem with­out affecting the directivity of the source, allowing flawless
vertical arraying of multiple MQV modules

A high power 2-inch exit/75mm voice coil compression driver
is mounted on a constant directivity horn for consistent,
accurate dispersal of HF information.

APPLICATIONS

The MQV1366 is engineered as a full range component for
very large format arrays and is an effective tool in large­scale permanent installations. Comprehensive mounting
points allow for flexible installation.

Applications include:

Large Church
Large Arenas
Stadiums

The three-way full range loudspeaker system shall incorpo­rate a 15-in woofer (vented), a 10-in cone MF transducer,
and a 2-in exit compression driver HF transducer.

The MF driver shall be loaded into a midrange horn con­structed of 3mm birch plywood reinforced with high density
polyurethane foam. The MF horn shall incorporate a radial
phase plug. The HF driver shall be loaded on constant direc­tivity horn with a nominal coverage pattern of 60° (h) x 60°
(v).

System frequency response shall vary no more than ±3 dB
from 50 Hz to 16 kHz measured on axis. The midrange fre­quency section shall produce a Sound Pressure Level (SPL) of
109 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 high frequency section shall produce
a Sound Pressure Level (SPL) of 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
midrange frequency section shall handle 400 Watts of ampli­fier power (AES Standard) and shall have a nominal imped­ance of 8 Ohms. The high frequency section shall handle 200
Watts of amplifier power (AES Standard) and shall have a
nominal impedance of 8 Ohms.

The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of 15mm thickness void-free cross-grain­laminated Baltic birch plywood and shall employ extensive
internal bracing. It shall be finished in wear-resistant tex­tured black paint. Input connectors shall be 1x 6-terminal
barrier strip and one Neutrik NL8 Speakon. A total of sixteen
3/8"-16 threaded mounting points (4 each top, bottom and
sides) shall be provided. The front of the loudspeaker shall
be covered with a powder coated perforated steel grill.

The three-way full range loudspeaker shall be the EAW model
MQV1366.
