A coupling system (10, 110) comprising coupling means (11, 111) for coupling at least two loudspeaker housings (2, 102) together, designed to couple the loudspeaker housing (2, 102) in such a manner that the loudspeaker housings (2, 102) will extend at a predetermined angle (3, 103) relative to each other in a hoisted position, further comprising setting means (12, 112) for setting said predetermined angle (3, 103), when the loudspeaker housings (2, 112) are in a non-hoisted, stretched position, wherein the coupling system (10, 110) is further designed for coupling the loudspeaker housings (2, 102) in such a manner that said loudspeaker housings (2, 102), upon being moved from the non-hoisted position to the hoisted position, will move under the influence of gravity from the stretched position to the position in which the loudspeaker housings (2, 102) extend at said pre-determined angle (3, 103).
