Abstract: A loudspeaker system including at least one loudspeaker unit, at least one mounting device, wherein the at least one loudspeaker unit is connectable to the at least one mounting device. The at least one mounting device is designed as an overlay, which has at least two countersunk grooves towards the interior, which correspond to protrusions on the exterior of the at least one loudspeaker unit when the overlay receives the at least one loudspeaker unit, wherein the at least two countersunk grooves each have a tangential offset approximately centrally, wherein in the path of the tangential offset there is a latch protrusion which gives the protrusions on the exterior of the at least one loudspeaker unit a tight fit.
