The present invention is an improved loudspeaker enclosure port (12) with internal longitudinal dividers (22) which help reduce turbulence in the port and control self-resonance. Preferred embodiments of the present invention comprise a central circular tube (24) or rod with radial dividers connecting the central tube to the internal wall (20) of the port. The internal longitudinal dividers of the present invention are thought to reduce air friction losses in the port and to reduce cross-flow turbulence in the port yielding a more responsive speaker with more uniform aerodynamic drag on the driver diaphragm.

La présente invention concerne une sortie d'enceinte de haut-parleur améliorée munie de diviseurs longitudinaux internes qui contribuent à réduire la turbulence dans la sortie et à contrôler la résonance propre de la sortie. Des forme de réalisation préférées de l'invention incluent un tube circulaire central ou tige muni de diviseurs radiaux reliant le tube central à la paroi interne de la sortie. Les diviseurs longitudinaux internes de l'invention sont conçus pour réduire dans la sortie les pertes cinétiques ainsi que les turbulences à flux transversaux, ce qui donne un haut-parleur plus sensible présentant une traînée aérodynamique plus uniforme sur la membrane de l'étage d'attaque
