Performance specifications of a typical production unit shall meet or exceed the following: frequency response, measured with swept sine wave input, shall be flat within ±3 dB from 35 Hz to 125 Hz and within -10 dB from 28 Hz to 170 Hz. Nominal dispersion, at -6 dB points, shall be Half Space. Nominal impedance shall be 8 Ohms. Power handling shall be 1000 Watts continuous, 4000 Watts peak. Sensitivity, measured on axis, mean averaged over stated bandwidth, shall be 95 dB, 1 Watt @ 1 metre. Maximum SPL (peak), measured at 1 metre with music program at stated amplifier input, shall be 131 dB. Dimensions: 600 mm high x 499 mm wide x 600 mm deep (23.6" x 19.6" x 23.6"). Net weight: 34.0 kg (75.0 lbs). The loudspeaker system shall be the TURBOSOUND TCX115B-WH. No other loudspeaker shall be acceptable unless submitted data from an independent test laboratory verifies that the above combined performance / size specifications are equalled or exceeded.
