The loudspeaker shall be of the full range, two-way, bi-amp/passive type, consisting of one 15″ (394 mm) LF driver and one 1.4″ (36 mm) HF compression driver. The loudspeaker shall be weather resistant for outdoor use, to rating standard IP54. 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 41 Hz to 18 kHz and within -10 dB from 35 Hz to 20 kHz. Nominal dispersion, at -6 dB points, shall average 90° H x 60° V, rotatable. Nominal impedance shall be HF: 6 Ohms, LF: 8 Ohms; passive: 8 Ohms. Power handling shall be HF: 75 Watts continuous, 300 Watts peak, LF: 600 Watts continuous, 2,400 Watts peak; passive: 600 Watts continuous, 2,400 Watts peak. Sensitivity, measured on axis, mean averaged over stated bandwidth, shall be 97 dB,
1 Watt @ 1 metre. Maximum SPL (peak), measured at 1 metre with music program at stated amplifier input, shall be HF: 134 dB, LF: 131 dB; passive: 131 dB. Dimensions: 834 mm high x 473 mm wide x 451 mm deep (32.8″ x 18.6″ x 17.8″). Net weight: 28.6 kg (63.1 lbs). The loudspeaker system shall be the TURBOSOUND TCS152/96-R. No other loudspeaker shall be acceptable unless submitted data from an independent test laboratory verifies that the above combined performance / size specifications are equaled or exceeded.
