The dual bi-amplified dedicated low frequency loudspeaker systems shall incorporate a four 12-in LF transducers and four 8-in LF transducers. The 12-in drivers shall be powered as two pairs, as shall the 8-in drivers. The system shall require an active external crossover at 250 Hz, 24dB Octave between the 8-in and 12-in drivers.

The 12-in drivers shall be mounted in a vented enclosure tuned for optimum low frequency response. The 8-in drivers shall be mounted in a sealed subenclosure. The four driver pairs shall be spaced to create a dipolar array such that the

total system shall provide 10 - 12 dB attenuation from 160 to 500 Hz at 90° off-axis (vertical).

System frequency response shall vary no more than ±3 dB from 58 to 500 Hz measured on axis. The 12-in drivers shall produce a Sound Pressure Level (SPL) of 104 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capa- ble of producing a peak output of 143.0 dB SPL on axis at 1 meter. The 12-in drivers shall handle 2000 Watts of amplifier power (AES Standard) and shall have nominal impedances of 2x 4 Ohms.

The 8-in drivers shall produce a Sound Pressure Level (SPL) of 104 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 139 dB SPL on axis at 1 meter. The 8-in drivers shall handle 800 Watts of amplifier power (AES Standard) and shall have nominal impedances of 2x 6 Ohms.

The loudspeaker enclosure shall be trapezoidal in shape. It shall be constructed of 1/2-in thickness void-free cross-grain- laminated Baltic birch plywood and shall employ extensive internal bracing. It shall be finished in wear-resistant tex- tured black paint. Input connector shall be 2x 4-terminal bar- rier strips. A total of sixteen 3/8”-16 threaded mounting points (4 each top, bottom and sides) shall be provided. The front of the loudspeaker shall be covered with a powder coat- ed perforated steel grille.

The dual bi-amplified dedicated low frequency loudspeaker systems shall be the EAW model MQTD812.
