DESCRIPTION
A 2-way biamp mid/high system in a trapezoidal enclosure.
Includes 2x horn-loaded 10-in midrange cone and a 2-in exit
compression driver on a 65 x 45 constant directivity horn.
APPLICATIONS
The MH662E Virtual Array mid/high loudspeaker is engineered
to combine with BH, BV or TD Series LF modules to create
true 3-way large format arrays. 3-way design dramatically
improves the quality of vocal reproduction while the cone-
driven large format midrange horn extends pattern control
into the lower octaves. It provides long throw and high out-
put in large scale permanent installations. Comprehensive
mounting/suspension points. Six year warranty.
Applications include:
Large Theaters
Concert Halls
Stadiums
Cathedrals
Large HOW’s
Dance Clubs

ARCHITECTURAL SPECIFICATIONS
The two-way mid/high loudspeaker system shall incorporate
2x 10-in cone MF transducers and a 2-in exit compression
driver HF transducer.
The MF drivers shall be loaded in a midrange horn constructed
of 3mm birch plywood reinforced with high density polyure-
thane foam. The MF horn shall incorporate a phase/displace-
ment plug. The HF driver shall be loaded on constant direc-
tivity horn with a nominal coverage pattern of 60°(h) x 45°
(v). An internal passive filter network shall provide system
equalization.
System frequency response shall vary no more than ±3 dB
from 160 Hz to 19 kHz measured on axis. The midrange fre-
quency 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 147 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 800 Watts of ampli-
fier power (AES Standard) and shall have a nominal imped-
ance of 4 Ohms. The high frequency section shall handle 200
Watts of amplifier power (AES Standard) and shall have a
nominal impedance of 15 Ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of 15mm thickness void-free cross-grain-
laminated Baltic birch plywood and shall employ extensive
internal bracing. It shall be finished in black catalyzed poly-
urethane. Input connectors shall be 4-terminal barrier strip
and dual Neutrik NL4 Speakon. A total of sixteen 3/8"-16
threaded mounting/suspension points (4 each top, bottom
and sides) shall be provided. The front of the loudspeaker
shall be covered with a vinyl coated perforated steel grill.
The two-way mid/high loudspeaker shall be the EAW model
MH662E.
