Architecture & Engineering Specifications
The loudspeaker shall be of the three-way bi-amp passive type consisting of two 12" (315 mm) LF drivers and one 1.4" (35 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 20 kHz and within -10 dB from 35 Hz to 20 kHz. Nominal dispersion, at -6 dB points, shall average 100° H x 10° V. Nominal impedance shall be HF: 12 Ohms, LF: 8 Ohms. Power handling shall be MHF: 190 Watts continuous, 760 Watts peak, LF: 600 Watts continuous, 2400 Watts peak. Sensitivity, measured on axis, mean averaged over the stated bandwidth, shall be MHF: 114.5 dB, 1 Watt @ 1 metre, LF: 101 dB, 1 Watt @ 1 metre. Maximum SPL of 143 dB (Average Peak level over overlap bandwidth. Measured at 1 metre on axis with dedicated pre-set). Dimensions: 354 high x 810 wide x 490 mm deep (13.9 x 31.9 x 19.3"). Net weight: 50 kg (110.2 lbs). The loudspeaker system shall be the TURBOSOUND MV212-XV. 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.
