Abstract
A ceiling-mounted loudspeaker includes a horn-shaped enclosure, an acoustic driver, and a front module. The tubular or horn-shaped enclosure carries a slanted woofer or loudspeaker driver which radiates into an angled or slanted first opening. The tubular enclosure terminates at bottom in a second, circular opening substantially parallel to a second plane, wherein the woofer's slanted plane is inclined with respect to the second plane. The slanted woofer can be oval and radiates sound through the enclosure's interior lumen and outwardly through ports defined in a substantially circular baffle carrying the front module and connected to the second opening. The baffle carries a midrange and tweeter near the ceiling where they can provide enhanced sound dispersion.
