EAW MQH1344e specifications Features, Description, Application, Performance, Physical

FEATURES

•Full-range, 3-way system

•2x slot-loaded 15-in LF; horn-loaded 10-in MF; 2-in Neodymium HF

•LF woofers spaced for directional control to below 200 Hz

•Asymmetrical (down-angled) 40° x 40° beamwidth

DESCRIPTION

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.

APPLICATION

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.
