The 3-way full-range loudspeaker shall incorporate 2x 15-in slot-loaded woofers, a 10-in MF cone with Radial Phase Plug™, and a 2-in exit/3-in diaphragm HF compression driver. The MF and HF devices shall be loaded on asymmetrical, down- angled horns with a 40° x 60° beamwidth. The LF woofers shall be optimally spaced to provide significant off-axis at- tenuation to below 200 Hz.

System frequency response shall vary no more than 63 dB from 75 Hz to 15 kHz measured on axis. The lower LF section shall produce a sound pressure level of 92 dB SPL on axis at 1 meter with a power input of 1 watt, and shall be capable of producing a peak output of 126 dB SPL on axis at 1 meter. The upper LF section shall produce a sound pressure level of 94 dB SPL on axis at 1 meter with a power input of 1 watt, and shall be capable of producing a peak output of 128 dB SPL on axis at 1 meter. The MF section shall produce a sound pressure level of 110 dB SPL on axis at 1 meter with a power input of 1 watt, and shall be capable of producing a peak output of 142 dB SPL on axis at 1 meter. The HF section shall produce a sound pressure level of 109 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 dB SPL on axis at 1 meter. Both LF sections shall handle 600 watts of amplifier power (AES Standard) and shall have a nominal impedance of 8 ohms. The MF section shall handle 400 watts of amplifier

Manufacturing tolerances are +/-0.13 ans +/-1°

The loudspeaker enclosure shall be trapezoidal in shape. It shall be constructed of exterior grade Baltic birch plywood and shall employ extensive internal bracing. It shall be fin- ished in wear-resistant textured black paint. Input connec- tors shall be a terminal strip. A total of 16x 3/8”-16 threaded mounting/suspension points (4 each top, bottom, and sides) shall be provided. The front of the loudspeaker shall be cov- ered with a powder coated perforated steel grille.

The 3-way full-range loudspeaker shall be the EAW model MQH1346e.
