IMPACT
80 Architects' and Engineers' Specifications
The system shall be of the two-way passive type consisting of one 8"
(203mm) low frequency loudspeaker 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 ±4dB from 70Hz to
20kHz. Nominal dispersion, at -6dB points, shall average 80 degrees
horizontal x 80 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 93dB.
Maximum SPL (peak) measured with music program at stated amplifier
input shall be 118dB. Dimensions: 480mmH x 295mmW x 250mmD (18.9"H x
11.6"W x 9.8"D). The loudspeaker system shall be the Turbosound
IMPACT 80. 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.
