TQ-445DP Architects' and Engineers' Specifications
The loudspeaker shall be of the self-powered, three way, bi-amplified type, consisting of one reflex loaded 12" (305mm) low frequency loudspeaker in a vented trapezoidal enclosure, one 6.5" (165mm) mid frequency loudspeaker loaded with a TurboMid device and a 1" (25mm) high frequency compression driver mounted co-axially to the low frequency loudspeaker. The integral power amplifier module shall provide two channels of Class D amplification, output limiting and equalisation incorporating frequency responses optimised for speech and music. Performance specifications of a typical production unit shall be: Frequency response, measured with swept sine wave input, shall be flat within ±4dB from 55Hz to 20kHz. Nominal dispersion, at -6dB points, shall average 60 degrees horizontal by 40 degrees vertical. Maximum SPL (peak) measured with music program at stated amplifier power shall be 137dB. Dimensions: 588mmH x 409mmW x 363mmD (23.1" x 16.1" x 14.3"). Weight: 34.5kgs (75.9lbs). The loudspeaker shall be the Turbosound TQ-445DP. 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. A range of flying and lifting hardware shall be available.
