Architect's & Engineer's Specifications

The loudspeaker system shall have an operating bandwidth of 64 Hz to 18 kHz. The nominal system output level shall be 91 dB when measured at a distance of one meter with an input of one Watt, when crossed over electronically. The nominal impedance of the enclosure shall be 8 Ohms. The maximum continuous power handling of the system shall be 200 Watts, maximum program power of 400 Watts and a peak power input of at least 800 Watts all with a minimum amplifer headroom of 3 dB. There shall be an externally accessible high frequency level adjust, selecting for an EQ position of outdoor, or indoor EQ, with the indoor EQ at 2 dB less high frequency output than the outdoor position. The enclosure shall be constructed of weather-resistant advanced technology composite fiber panels, and finished in a textured hard-shell of black poly-urea coating. The overall system weatherization rating of the loudspeaker systems shall be IP56. The outside dimensions shall be 17.32 inches (440 mm) high by 13.94 inches (354 mm) wide by 10.94 inches (278 mm) deep. The full-length grille shall have a triple-layer construction, consisting of perforated stainless steel outer layer, a hydrophobic cloth middle layer, and a reticulated foam inner layer, so as to provide excellent moisture protection to the drivers. The nominal radiation geometry shall be 75 degrees in the horizontal plane, and 75 degrees in the vertical plane. The input connections shall consist of a corrosion-resistant screw terminal barrier strip for raw wire termination, which is in parallel with two Neutrik NL-4 type input jacks. A watertight cover plate with a gland nut shall be provided, for use with the barrier strip connection. The weight shall be 26 pounds (11.8 kg). The IP 56 rated loudspeaker system shall be a Peavey Elements model 108C or approved equivalent.
