The system shall be of the two-way passive type consisting of two 5" (127mm) low frequency loudspeakers and one 1" (25mm) high frequency 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 70Hz to 20kHz ±4dB. Nominal dispersion, at -6dB points, shall average 100 degrees horizontal by 60 degrees vertical. Nominal impedance shall be 8 ohms. Power handling shall be 125 watts r.m.s., 250 watts program, 315 watts peak. Sensitivity, measured with 1 watt input at 1 metre distance on axis, mean averaged over stated bandwidth, shall be 90dB. Maximum SPL (peak) measured with music program at stated amplifier input shall be 120dB. Dimensions: 210mmH x 494mmW x 190mmD (8.3"H x 19.5"W x 7.5"D). The loudspeaker system shall be the Turbosound TCS-30. No other loudspeaker shall be acceptable unless submitted data from an independent test laboratory verify that the above combined performance / size specifications are equalled or exceeded.
