Abstract

Dispositifs de diffusion sonore comportant deux pavillons de section progressive et contenant un ou plusieurs haut-parleurs de dimension standard. Il est destiné de par sa conception à augmenter la réponse aux plus basses fréquences du spectre sonore. Le souci de réduire la taille du meuble amène à faire appel à un système de retard constitué d'un conduit long intermédiaire pouvant posséder à une extrémité une ou plusieurs membranes passives.
