6.0 MH690iE SYSTEM
6.1 MH690iE Architectural Specifications
The two-way midrange/high frequency loudspeaker system shall incorporate a10 inch
mid frequency cone transducer and a compression driver mounted to a constant
directivity high frequency horn. The system shall meet the following performance
criteria: Frequency Response of 200 Hz to 19 kHz ±3 dB; Axial Sensitivity (1W @ 1m)
of 108 dB SPL; 100 hour sine wave Power Handling of 175 Watts (MF), 80 Watts (HF);
Horizontal coverage of 90°between -6 dB points; Vertical coverage of 45°between -
6 dB points.
The system’s mid frequency driver shall be loaded into a constant horizontal coverage
horn constructed of 3 mm cross-grain-laminated birch hardwood. The horn flare shall
be reinforced with high density polyurethane foam and shall incorporate a center
displacement plug. The high frequency driver shall utilize a titanium diaphragm.
The trapezoidal enclosure shall be constructed of void-free cross-grain-laminated birch
plywood and shall have internal bracing. It shall be finished in a black catalyzed poly-
urethane coating. All external hardware shall be stainless steel or shall be coated to
protect against rust and corrosion. The front of the system shall be covered with a
protective perforated steel grill assembly coated with vinyl to dampen resonance.
Hanging fixture attachment points shall be installed in the top and bottom of the
enclosure and mating clips shall be included with the system. Cabinet sides shall be
tapered in such a way as to simplify construction of arrays.
The two-way midrange/high frequency loudspeaker system shall be the EAW model
MH690iE.
