The low frequency loudspeaker systems shall incorporate 2x 12-in plus 2x 8-in LF transducers. Each driver pair shall be spaced so as to create a tuned dipolar array. The driver pairs shall require an active crossover at 250 Hz, 24 dB/octave. The system shall provide 10-12 dB attenuation 90° off axis (v) from 160 Hz to 500 Hz.
System frequency response shall vary no more than ±3 dB from 58 Hz to 500 Hz measured on axis. The 12-in driver pair shall produce a Sound Pressure Level (SPL) of 101 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable

of producing a peak output of 137 SPL on axis at 1 meter. The 12-in driver pair shall handle 1000 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 2x 8 Ohms.
The 8-in driver pair shall produce a Sound Pressure Level (SPL) of 101 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 133 SPL on axis at 1 meter. The 8-in driver pair shall handle 400 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 2x 12 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 textured black paint. Input connectors shall be dual four-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 low frequency loudspeaker shall be the EAW model MQTD412.
