Title (EN) MANIFOLD LOUDSPEAKER SYSTEM
(FR) SYSTEME ACOUSTIQUE A HAUT-PARLEURS MULTIPLES
Abstract:
(EN) A loudspeaker system especially for use in the mid/bass frequency range comprises a cabinet in which loudspeakers are mounted in mutually opposed points with an acute angle therebetween. The speakers may form respective mutually opposed banks. The enhanced sound quality without distortion or null zones, two such cabinets may be mounted side by side with a spacing between the centre points of the horns of the respective cabinets being 550-700 mm.
(FR) Un système de haut-parleurs, notamment utile dans les plages de fréquences moyennes/basses comprend une enceinte dans laquelle les haut-parleurs sont montés à des points mutuellement opposés, formant un angle aigu entre eux. Les haut-parleurs peuvent former des rangées mutuellement opposées. Afin d'obtenir un son de qualité améliorée sans zones nulles ou de distorsion, deux de ces enceintes peuvent être montées l'une à côté de l'autre, l'écartement entre les centres des cornets des enceintes respectives étant compris entre 550 et 700 mm.
