ViRAY
The system is to consist of a 3-way loudspeaker cabinet, either actively or passively separated, which is driven and protected by a special controller output stage. The loudspeaker should contain two 8 inch cone loudspeakers in a bass reflex tuned cabinet for the low frequency range. The used loudspeakers should be impregnated weatherproof. In the mid-range, a pressure chamber driver with a 3.5-inch ring diaphragm arranged coaxially in front of the high-frequency driver is to operate. In the high frequency range, a pressure chamber driver with 1.75 inch ring diaphragm is to work. The pressure chamber drivers used should be coupled to a common planar wave waveformer. The continuous load capacity of the system should be 600 watts RMS. The loudspeaker should have a nominal impedance of 16 Ohm in the LF path and 16 Ohm in the MF/HF path. The usable system bandwidth should be 55 Hertz to 22,000 Hertz (-6 dB). The system should be usable with a horizontal dispersion angle of 80°, 120° or asymmetrical 100°. When used alone, the loudspeaker should have a vertical dispersion angle of symmetric 10°. In combination with other loudspeakers of the same type in a line source array configuration, the vertical dispersion angle should depend on the number of loudspeakers used and their angle to each other. The angle of the elements to each other should be minimum 0° and maximum 10° within the system. The maximum peak sound pressure level should be 142 dB SPL, measured with pink noise at a distance of 1 m, under half-space conditions and with a crest factor of 6. The speaker cabinet should be made of birch multiplex and sealed with a weather and moisture resistant polyurea coating (PU). The front of the loudspeaker should be provided with a ball impact resistant protective grille, which is backed with acoustically neutral foam. Its physical dimensions should be 674 mm in width, 242 mm in height and 362 mm in depth. The weight of the loudspeaker should be 25.5 kg. The loudspeaker should have an integrated 3-point suspension with which special accessories can be mounted. It should be able to be connected without accessories to loudspeakers of the same type, as well as to be mounted to a stacked or suspended line source using accessories with loudspeakers of the same or different type. The speaker should be connected using a 4-pin SpeakON socket and a permanently mounted 4-pin SpeakON Link cable. The manufacturer's warranty shall be 5 years.
