KTV-SOUNDBAR

The system should consist of an actively separated 2.1-way stereo loudspeaker, which is driven and protected by a special control amplifier. The loudspeaker should contain an 8 inch loudspeaker for the bass range on the right and left side in a common bass reflex tuned cabinet. The used loudspeakers should be impregnated weatherproof. In the high-frequency range, a pressure chamber driver with a 1.75 inch ring diaphragm is to operate in each case, which is located in a coaxial arrangement with the bass loudspeakers. The pressure chamber drivers used should be coupled to a symmetric horn with a 100° beam angle. The usable system bandwidth should be able to work as a true full-range system by using a 12-inch loudspeaker as a low bass extension. In the low bass range, the system should have an omnidirectional dispersion characteristic. The continuous load capacity of the system should be 1,000 watts RMS. The loudspeaker should have a nominal impedance of 4 Ohm. The usable system bandwidth should be 35 Hertz to 20,000 Hertz (-4 dB). The maximum peak sound pressure level should be 133 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 front of the loudspeaker should be provided with a ball-proof protective grille, which is backed with acoustically neutral foam. Its physical dimensions should be 1320 mm in width, 342 mm in height and 200 mm in depth. The weight of the loudspeaker shall be 30 kg. The loudspeaker should have M6 mounting points with which special accessories can be mounted. It should be possible to mount the loudspeaker on a wall with accessories straight or inclined up to 45°. The loudspeaker box is to be connected via an 8-pin SpeakON socket. The manufacturer's warranty should be 5 years.
