Abstract

L'invention concerne l'acoustique. Elle concerne en particulier une enceinte acoustique perfectionnée du type comprenant un boîtier sensiblement parallélépipédique et deux haut-parleurs, l'un pour les graves, l'autre pour les aigus, caractérisée en ce que le boîtier est rempli en partie par un matériel absorbant, le haut-parleur pour les aigus etant fixé sur l'une des parois verticales, cette dernière étant percée d'une ouverture circulaire dans laquelle s'étend le haut-parleur pour les graves, celui-ci étant porté par une plaque reliée à ladite paroi par des barrettes de manière à ménager au moins un conduit s'ouvrant vers le bas. Elle s'applique notamment aux enceintes acoustiques.
