55-20000Hz, 89dB, 75W, 8Ω, IP65, White

The loudspeaker shall be a surface mount, two-way, full-range system, with an internal passive crossover. The loudspeaker's low-frequency transducer shall be a 5.25" (133 mm) woofer, with a weather resistant polypropylene cone, and a 1" (25 mm) voice-coil. The loudspeaker's high-frequency transducer shall be a 0.75" (20 mm) Ferro fluid cooled driver, coupled to a baffle-integrated waveguide.

The loudspeaker system shall meet the following performance criteria: Power handling, 75 W of IEC 60268-5 continuous pink noise (6 dB crest factor); Frequency response, 55 Hz - 20 kHz (-10 dB from rated sensitivity); Sensitivity, 89 dB at one watt, 100 Hz - 10 kHz at one meter; Impedance, 8 Ohm nominal, 6.5 Ohm minimum.

The loudspeaker shall have a transformer suitable for use on 70 V or 100 V distributed lines. The transformer shall have taps ranging from 7.5 W to 60 W, plus an 8 Ohm bypass, selectable using a switch on the rear of the enclosure. The 8 Ohm bypass selection shall be protected by a safety screw.

The high-frequency transducer shall drive a waveguide to cover evenly 90° horizontally by 90° vertically. The finish shall be black (RAL 9004) or white (RAL 9003). The grille shall be marine grade aluminum. The loudspeaker shall be adjustable over a range of 90° vertically, using a U-Bracket.

The loudspeaker shall have an included U-Bracket. The U-Bracket shall be marine grade aluminum. Electrical connections shall be through a 4-pin detachable Euroblock connector on the input panel. The loudspeaker should include an IP65 weather cover for the input panel.
