The total system shall meet the following performance criteria: Frequency Response of 100 - 18k Hz ±3 dB; Axial Sensitivity (1 W @ 1 m) of 94 dB SPL (LF); 100 hour sine wave Power Handling of 120 Watts , AES method Power Handling of 300 Watts; Horizontal coverage of 120 degrees between 6dB down points; Vertical coverage of 80 degrees between 6dB down points. The system’s two low frequency drivers shall be loaded into a single vented enclosure that provides optimally controlled acoustic diaphragm loading. An internal passive frequency dividing network shall provide a fourth order acoustic crossover between the low and high frequency subsystems and shall incorporate system equalization. The crossover shall be designed so that maximally flat frequency response is obtained. The enclosure shall be trapezoidal and constructed of void-free crossgrain-laminated birch plywood with internal bracing. It shall be finished in a black catalyzed polyurethane coating. The front of the system shall be covered with a protective perforated steel grill assembly coated with vinyl to dampen resonance. Mounting hardware attachment points shall be located on the top and bottom of the enclosure. Attachment points for Omnimounttm brand 75 series mounting hardware shall be located on the rear of the enclosure. The two-way full range loudspeaker system shall be the EAW model JF50.
