Architecture and Engineering Specifications
The speaker shall be of the full range, two-way passive type consisting of one 10" (250 mm) LF ferrite driver with 2.5'' voice coil and one 1" (25 mm) HF neodymium compression driver with 1.7'' voice coil. 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 80Hz to 20 kHz and within -10 dB from 50 Hz to 20 kHz. Nominal dispersion, at -6 dB points, shall average 80° H x 50° V, rotatable. Nominal impedance shall be passive: 8 Ohms.
Power handling shall be passive: 350 Watts continuous, 1,400 Watts peak. (LF: 350 W continuous HF: 50 W continuous FR: 400 W continuous) Sensitivity, measured on axis, mean averaged over the stated bandwidth, shall be 96 dB, 1 Watt @ 1 metre. Maximum SPL of 134 dB in passive mode (FR rating, Average Peak level over overlap bandwidth. SPL level at 1 m under free field conditions, using pink noise with crest factor 4, with dedicated preset).
Dimensions: 545 mm high x 340 mm wide x 320 mm deep (21.56 x 13.4, 12.6"). Net weight: 17.8kg (39.24lbs). The loudspeaker system shall be the Turbosound PQ10. 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.
