Architecture & Engineering Specifications
The loudspeaker shall be of the full range, two-way passive type consisting of one 12" (305 mm) LF driver and one 1" (25 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 100 Hz to 18 kHz and within -10 dB from 68 Hz to 20 kHz. Nominal dispersion, at -6 dB points, shall average 90° H x 60° V, rotatable. Nominal impedance shall be 8 Ohms. Power handling shall be 300 Watts continuous, 1,200 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 128 dB. Dimensions: 552 mm high x 406 mm wide x 368 mm deep (21.7" x 16.0" x 14.5"). Net weight: 18.3kg (40.2 lbs). The loudspeaker system shall be the Turbosound TCX122. 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.
