The compact loudspeaker shall consist of a 10 inch (250 mm) low frequency transducer with 2.5 inch (65 mm) voice coil and a 1 inch (25.4 mm) exit 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 96 dB-SPL. Usable frequency response shall extend from 51 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 300 Watts continuous power and 1,200 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 compression driver shall be capable of even coverage at a nominal 90° horizontal through 60° vertical distributed pattern. The horn shall be rotatable. The enclosure shall be constructed from prime-grade 15 mm plywood. The loudspeaker shall be equipped with a total of sixteen (16) 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.
