Architect's & Engineer's Specifications

The ultra-compact coaxial loudspeaker shall consist of a 5 inch (130 mm) low frequency transducer with 1.5 inch (38 mm) voice coil and a 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 4.0V input, shall be 92 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 16 Ohms. Rated power capacity shall be at least 100 Watts continuous power and 400 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 three (3) 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 7.28 inches (185 mm) high by 7.28 inches (185 mm) wide by 8 inches (203 mm) deep weighing 11.6 pounds (5.3 kg). The finish shall be a paintable lightly textured black or white. The ultra-compact coaxial loudspeaker shall be the Crest Audio CPL 5C+ with included U-Bracket or approved equivalent.
