Architect's & Engineer's Specifications The loudspeaker system shall have an operating bandwidth of 68 Hz to 18 kHz. The nominal system output level shall be 95 dB when measured at a distance of one meter with an input of one Watt. The nominal impedance of the enclosure shall be 8 Ohms. The maximum continuous power handling of the system shall be 500 Watts, maximum program power of 1,000 Watts and a peak power input of at least 2,000 Watts, all with a minimum amplifier headroom of 3 dB, and proper infrasonic filtering. 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 1/2 inch thick weather-resistant advanced technology composite fiber panels, and finished in a textured hard-shell of black poly-urea coating. The outside dimensions shall be 30.69 inches (780 mm) high by 18 inches (457 mm) wide by 17.5 inches (445 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 woofer shall be of a weather-resistant construction and materials, able to withstand direct exposure to moisture for long periods of time. The speaker system shall have an IP rating of IP56, when properly installed, according to the instruction. The nominal radiation geometry shall be 105 degrees in the horizontal plane, and 60 degrees in the vertical plane. The horn shall be rotatable in 90 degree increments so that the broad portion of the horn pattern can be changed to the other orientation. The weight shall be 62 pounds (28.2 kg). The loudspeaker system shall be a Peavey Elements model 115C 105X60 or approved equivalent.
