EAW BH2312 User Manual
PRELIMINARY
• Low frequency array loudspeaker
• Three horn-loaded 12 inch woofers
• Beamwidth at upper frequency limit matches MQ2343D
• For permanent installation only
• Digital signal processor required for specified performance
The BH2312 uses three horn load ed 12 inch con es m oun ted in
a trapezoidal en closur e . I ts fr equen cy r espon se has been optimized for use as a dedicated low fr equency system when used
with a companion MQ mid/high loudspeaker. Each 500 watt,
8 ohm driver has its own connection s on the input pan el. 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.
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.
