摘要： The invention concerns a mounting system for mounting a loudspeaker cabinet on a wall. The mounting system includes a wall mount for mounting on a wall and a loudspeaker fitting for mounting on or in a loudspeaker cabinet. The fittings are designed such that there may be provided a mechanical fixing of the loudspeaker cabinet on the wall simultaneously with the connecting terminals of the loudspeaker cabinet automatically achieving contact with the loudspeaker cable. This is achieved by mounting the loudspeaker cable in electric connecting terminals on the wall mount, which includes means for transmitting the electric signal from the signal source of the loudspeaker cable via electric contact faces on the coupling member in the wall mount and via electric contact faces on coupling terminals in the loudspeaker fitting to the connection terminals of the loudspeaker cabinet.
