Architect's & Engineer's Specifications

The compact coaxial loudspeaker shall consist of two 5 inch (130 mm) low frequency transducers with 1.5 inch (38 mm) voice coil and one coaxially mounted 1 inch (25.4 mm) exit Neodymium compression driver with a 1.4 inch (36 mm) voice coil and a frequency dividing network installed within the enclosure. Performance specifications of a typical production unit shall be: Measured sensitivity SPL at 1 m (3.3ft) with 2.83V input, shall be 94 dB-SPL. Usable frequency response shall extend from 91 Hz to 20 kHz (10 dB below rated sensitivity, in full space, with no external equalization). Nominal impedance shall be 8 Ohms. Rated power capacity shall be at least 200 Watts continuous power and 800 Watts peak power, defined as 6 dB above a test signal of filtered random noise. The system shall be protected against damage from occasional over-powering limiting the power to the network and transducers. The coaxial neodymium compression driver shall be capable of even coverage at a nominal 80° horizontal through 80° vertical distributed pattern. The enclosure shall be constructed from prime-grade 15 mm plywood. The loudspeaker shall be equipped with a total of seven (7) suspension points. The grille shall be of heavy-duty steel backed with acoustically transparent foam. The external wiring shall be via either two 4-pin twist-lock or one 4-pin Euroblock connectors. The loudspeaker shall be 14.96 inches (380 mm) high by 7.01 inches (178 mm) wide by 7.4 inches (188 mm) deep weighing 20 pounds (9.1 kg). The finish shall be a paintable lightly textured black or white. The compact coaxial loudspeaker shall be the Crest Audio CPL 25C+ with included U-Bracket or approved equivalent.
