Claim 0:
1. An acoustic horn arranged to be fastened between a cabinet of a generic loudspeaker enclosure in which at least one loudspeaker is incorporated, and an outer casing suitable for covering the cabinet at least in part, the outer casing being suitable for presenting differing shapes and/or dimensions and including a hole set having at least one hole, the acoustic horn presenting a shape and/or dimensions that depend on the shape and/or the dimensions of the outer casing, the acoustic horn having an outer face, an inner face, and an inside peripheral surface defining a through cavity formed through the thickness (e) of the horn and having an outer edge defined on the outer face and an inner edge defined on the inner face, the acoustic horn being arranged in such a manner that when the acoustic horn, the cabinet, and the outer casing are assembled together, the inner face is in contact with the cabinet in such a manner that the inner edge surrounds a diaphragm of the loudspeaker and the outer face is in contact with the outer casing in such a manner that the hole set having at least one hole in the outer casing lies inside an area defined by the outer edge, the horn thus being arranged in such a manner that the inside peripheral surface guides sound produced by the loudspeaker towards the outside via the hole set having at least one hole in the outer casing, the through cavity flaring from the inner edge towards the outer edge so as to guide sound towards at least one first direction, the acoustic horn having a shape that is symmetrical relative to a first plane parallel to the thickness of the horn and including the first direction, with the exception of fastener means for fastening it to the cabinet, which need not necessarily be symmetrical relative to said first plane.
