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 ±3dB from 89Hz
to 20kHz, and within ±10dB from 64Hz to 20kHz. Nominal dispersion, at -6dB points, shall average 100
degrees horizontal x 70 degrees vertical. Power handling shall be 80 watts continuous, 160 watts program. Sensitivity, measured with 1 watt input at 1 metre distance on axis, averaged over stated bandwidth shall be 90dB. Maximum SPL (peak) measured
with music program at stated amplifier input shall be 115dB.
Dimensions: 300mmH x 164mmW x 158mmD (11.8"H x 6.5"W x 6.2"D).
Weight: 3.5kg (7.7lbs). The loudspeaker system shall be the
Turbosound Impact 55T. 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.
