DESCRIPTION

A 2-way biamp mid/high system in a trapezoidal enclosure.
Includes a horn-loaded 10-in midrange cone and a 2-in exit
compression driver on a 65 x 45 constant directivity horn.

APPLICATIONS

The MH660E 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 cone­driven large format midbass horn extends pattern control
into the lower octaves. An effective tool 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
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 phase/
displacement plug. The HF driver shall be loaded on con­stant directivity 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 200 Hz to 19 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 10 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 black catalyzed poly­urethane. 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
MH660E.
