A generic loudspeaker enclosure adapted to be incorporated in modular equipment that, in addition to the loudspeaker enclosure, comprises at least one electronic additional module comprising at least one electronic card, the generic loudspeaker enclosure comprising: - a cabinet comprising: o a main portion comprising a plurality of lateral faces (26, 27, 28, 29) of the cabinet and a first non-lateral face which is an upper face or a lower face of the cabinet, and ∘ a cover which closes the cabinet and forms a second non-lateral face of the cabinet, the second non-lateral face being opposite the first non-lateral face; the cabinet comprising internal partitions which extend vertically from an inside wall of the first non-lateral face of the cabinet and defining a plurality of acoustic chambers (41, 42) that are sealed, distinct, and separated from one another by said internal partitions, each acoustic chamber comprising an orifice (43, 44, 45) opening to the outside of the cabinet in a respective different direction; · a plurality of loudspeakers (47, 49; 51), each comprising a respective diaphragm, each loudspeaker being incorporated in a respective one of the acoustic chambers in such a manner that the diaphragm of said loudspeaker extends over the orifice, the plurality of loudspeakers comprising a plurality of first loudspeakers each integrated in a first acoustic chamber comprising a first orifice which opens to the outside at a separate lateral face of the cabinet, and at least one second loudspeaker integrated in a second acoustic chamber comprising a second orifice which opens to the outside at the first non-lateral face of the cabinet; · at least one first connector mounted in sealed manner on the cabinet, the first connector having contacts that are electrically connected to the loudspeakers, the first connector thus being arranged to connect the loudspeakers electrically to the electronic card of the electronic additional module via a second connector mounted on the electronic additional module and complementary to the first connector, the cabinet being made by plastic injection. - a cabinet comprising: o a main portion comprising a plurality of lateral faces (26, 27, 28, 29) of the cabinet and a first non-lateral face which is an upper face or a lower face of the cabinet, and ∘ a cover which closes the cabinet and forms a second non-lateral face of the cabinet, the second non-lateral face being opposite the first non-lateral face;
