Abstract

Système de haut parleur à voie centrale destiné à être utilisé avec un système acoustique à quatre voies 'Dolby'. Un premier (18) haut-parleur est monté sur le devant d'une enceinte (10). Des deuxième (12) et troisième (14) haut-parleurs dont les cônes sont plus grands que celui du premier (18) haut-parleur et dont la gamme de fréquences est inférieure à celle du premier (18) haut-parleur, sont montés sur le devant d'une enceinte (10) de chaque côté du premier (18) haut-parleur, suivant un arc de 40 dégres environ dans le plan vertical à l'arrière du premier (18) haut-parleur. Cette disposition permet de minimiser la suppresion destructrice du son émanant des haut-parleurs à voie centrale qui ne sont pas très éloignés.
