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
