Description The BH2312 uses three horn-loaded 12 inch woofers mounted in a trapezoidal enclosure. Its frequency response has been optimized for use as a dedicated low frequency system when used with a companion MQ mid/high loudspeaker. Each 500 watt, 8 ohm driver has its own connections on the input panel. This allows the drivers to be connected in parallel to one amplifier channel or connected individually to separate amplifier channels. The enclosure features a comprehensive system of 3/8-16 threaded suspension points.

Applications The BH2312 is designed to work with the high Q MQ2343D mid/high loudspeaker to create a full range audio system capable of tremendous output. The three horn-loaded 12 inch drivers provide maximum impact from 45 Hz to 300 Hz over great distances. Use in multiples of three will optimize LF response and smoothness. The BH2312 is also compatible with any MQ2300 Series mid/high product.
