A 3-way, quad-amplified full-range system in a vented trape-
zoidal enclosure. Includes dual, slot-loaded 15-in woofers, a
horn-loaded 10-in MF cone with Radial Phase Plug™, and a 2-
in exit/3-in diaphragm Neodymium compression driver. The
MF and HF horns provide an asymmetrical 40° x 40°
beamwidth. The enclosure is vertically configured for array-
ing in horizontal rows, and features a comprehensive system
of 3/8”-16 threaded suspension points.

The MQH1344e represents a highly specialized approach
developed to solve difficulties in larger venues. It provides
unique, down-angled coverage by using specially designed
asymmetrical MF and HF horns. Dual 15-in woofers are sepa-
rated at an optimal distance to provide significant off-axis
attenuation to below 200 Hz. To avoid problematic lobing in
the upper LF range, discrete signal processing reduces the
input to one LF driver while allowing the other to continue to
work up into the lower midrange. This more evenly matches
the MF horns beamwidth while assisting in maintaining pat-
tern control through the entire crossover region. The
MQH1344e requires four separate amplifier channels (quad-
amplification) and digital signal processing in order to
achieve the pattern control described.
