• 90° x 40° beamwidth
• Vertically configured to create horizontal arrays
A dedicated mid/high system in a vented trapezoidal enclo-
sure. Includes a horn-loaded 10-in MF cone with Radial Phase
Plug™ and a 2-in exit/3-in diaphragm Neodymium compres-
sion driver. The MF and HF horns provide a nominal 90° x 40°
beamwidth. An internal passive crossover with jumpers on the
input panel allows user selection of either bi-amplified or
passive operation. In either case digital signal processing is
required to achieve specified performance. The enclosure
features a comprehensive system of 3/8”-16 threaded sus-
pension points.
The MQ1394e employs a no-compromise design where the mid
and high frequency horns are truly large enough to provide
optimal pattern control throughout each passband. The horns
feature a rigid but well-damped construction using wood
veneer backed by structural foam. The MQ1394e has been
designed to work with a complementary MQ1300 Series LF
loudspeaker to create a full-range audio system, but may also
be used without a LF complement for voice-only applications.
The enclosure is vertically configured for arraying in horizon-
tal rows. Horizontal arrays are typically used in venues, such
as houses of worship, where the array must address wide, fan-
shaped audiences.
Application Usage: Install
Houses of Worship Auditoriums
Theatres Arenas
Performing Arts Centers Stadiums

The 2-way mid/high loudspeaker shall incorporate a 10-in MF
cone with Radial Phase Plug™, and a 2-in exit/3-in diaphragm
HF compression driver. The MF and HF devices shall be loaded
on horns that provide a nominal 90°x 40°beamwidth. An
internal passive crossover network shall offer either passive or
bi-amplified operation, configurable via jumpers on the input
panel.
System frequency response shall vary no more than 63 dB from
250 Hz to 15 kHz measured on axis. When amplified using the
internal passive crossover network, the loudspeaker shall pro-
duce a sound pressure level of 109 dB SPL on axis at 1 meter
with a power input of 1 watt, and shall be capable of produc-
ing a peak output of 140 dB SPL on axis at 1 meter. It shall
handle 325 watts of amplifier power (AES Standard) and shall
have a nominal impedance of 8 ohms. When bi-amplified, the
MF section shall produce a sound pressure level 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 144 dB SPL on axis at
1 meter. It shall handle 400 watts of amplifier power (AES
Standard) and shall have a nominal impedance of 8 ohms. The
HF section shall produce a sound pressure level 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 137 dB SPL on axis at
1 meter. It shall handle 150 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 exterior grade Baltic birch plywood and
shall employ extensive internal bracing. It shall be finished in
wear-resistant textured black paint. Input connectors shall be
a terminal strip. A total of 16x 3/8”-16 threaded
mounting/suspension points (4 each top, bottom, and sides)
shall be provided. The front of the loudspeaker shall be cov-
ered with a powder coated perforated steel grille.
The 2-way mid/high loudspeaker shall be the EAW model
MQ1394e.
