Description
A dedicated mid/high system in a trapezoidal enclosure. Includes two horn-loaded 10 in MF cones and two 2 in exit/3 in diaphragm neodymium compression drivers for extremely high output. The MF and HF horns have a nominal 45° x 30° beamwidth. An internal passive crossover with jumpers on the input panel allows user selection of either bi-amplified or passive operation. In either case digital signal processing is required to achieve specified performance. The enclosure features a comprehensive system of 3/8"-16 threaded suspension points.

Applications
The MQ2343D employs a no-compromise high "Q" design where the mid and high frequency horns are truly large enough to provide optimal pattern control throughout each passband. The MQ2343D has been specifically designed to work with the horn-loaded BH2312 LF loudspeaker to create a full-range audio system. It may also be used with the MQ2315, MQ2412, and MQTD415 LF loudspeakers, or without a LF complement for voice-only applications. Dual HF components produce greater output than comparably-sized MQ2300 Series products for long throw applications.
