Architecture & Engineering Specifications
The speaker shall be of the full range, two-way switchable bi-amp/passive type consisting of one 12" (312 mm) LF driver and one 1.4" (36 mm) HF compression driver. 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 50 Hz to 18 kHz and within -10 dB from 45 Hz to 20 kHz. Nominal dispersion, at -6 dB points, shall average 90° H x 40° 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 96 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: 130 dB; passive: 130 dB. Dimensions: 834 mm high x 399 mm wide x 425 mm deep (32.8" x 15.7" x 16.7"). Net weight: 26.5 kg (58.4 lbs). The loudspeaker system shall be the Turbosound TCS122/94. 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.
