TCS-121C Architect's and Engineer's Specifications
The system shall be of the full range two-way type consisting of one 12" (305mm) low frequency loudspeaker and one 1" (25mm) high frequency driver on a 70°H x 40°V HF horn. 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 ±4dB from 60Hz to 20kHz. Nominal dispersion, at -6dB points, shall average 70° horizontal x 40° vertical. Nominal impedance shall be 8 ohms. Power handling shall be 300 watts, r.m.s., 600 watts program. Sensitivity, measured with 1 watt input at 1 metre distance on axis, mean averaged over stated bandwidth, shall be 97dB. Maximum SPL (peak) measured with music program at stated amplifier input shall be 128dB. Dimensions: 553mmH x 407mmW x 352mmD (21.8"H x 16"W x 13.9"D). Weight: 19kg (41.8lbs). The loudspeaker system shall be the Turbosound TCS-121C. 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
