Abstract
a. Enceinte à moteurs de haut-parleurs multiples. b. Enceinte caractérisée en ce qu'elle se compose d'un moyen définissant une cavité formée avec un ensemble correspondant d'ouvertures de moteurs recevant chacun un moteur correspondant d'un haut-parleur ainsi que des accessoires acoustiques, le moyen définissant la cavité ayant au moins une masse d'ouverture pour recevoir un moyen donnant une masse acoustique pour que la résonance avec les accessoires acoustiques à la fréquence de résonnance prédéterminée masse-accessoires se trouve dans la plage des basses fréquences audio, et un moyen pour réduire le coefficient Q du circuit résonnant formé par le moyen définissant la cavité.
