TQ-440SP 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 AB 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 75Hz to 17kHz (music setting) and 90Hz to 17kHz (speech setting). 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 134dB. Dimensions: 588mmH x 409mmW x 363mmD (23.1" x 16.1" x 14.3"). Weight: 39kgs (85.8lbs). The loudspeaker shall be the Turbosound TQ-440SP. 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.
