The system is to consist of a passively separated 2-way loudspeaker, which is driven and protected by a special controller output stage. The loudspeaker should contain an 8 inch loudspeaker in a bass reflex tuned cabinet for the low frequency range. The used loudspeakers should be impregnated weatherproof. In the high-frequency range, a pressure chamber driver with 1.5-inch ring diaphragm is to operate. The pressure chamber driver used should be coupled to a symmetrical horn. Its radiation characteristic should be 90°. The continuous load capacity of the system shall be 220 watts RMS. The loudspeaker should have a nominal impedance of 8 Ohm. The usable system bandwidth should be 70 Hertz to 30,000 Hertz (-3 dB). The maximum peak sound pressure level should be 124 dB, measured with pink noise at a distance of 1 m, under half-space conditions and with a crest factor of 6. The loudspeaker cabinet should be made of birch multiplex and sealed with a weather- and moisture-resistant polyurea coating (PU). The trapezoidal housing should have inclinations of 55°, 25° and 20° respectively, which make the use as a stage monitor more flexible. The front of the loudspeaker should be equipped with a ball-proof protective grille, which is backed with new acoustic foam. Its physical dimensions should be 230 mm in width, 471 mm in height and 260 mm in depth. The weight of the loudspeaker should be 9.5 kg. The loudspeaker should have M6 and M8 mounting points with which special accessories can be mounted. The speaker should have an integrated stand flange. With optional flying brackets the loudspeaker box can be mounted in horizontal and vertical direction. The system should be available in left and right speaker versions. The loudspeaker should be connected via two 4-pole SpeakON sockets. An integrated 'Human-EQ' filter shuttering on the connection panel should optimize the frequency image of the loudspeaker for pure speech applications when activated. The manufacturer's warranty should be 5 years.
