The system shall be of the two-way passive type consisting of two 5" (127mm) low frequency loudspeakers and one 0.5" (14mm) high frequency tweeter. 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 120 degrees horizontal x 120 degrees vertical. Nominal impedance shall be 8 ohms. Power handling shall be 120 watts r.m.s., 240 watts program, 300 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: 426mmH x 162mmW x 140mmD (16.8"H x 6.4"W x 5.5"D). The loudspeaker system shall be the Turbosound TCS-20. 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.
