ABSTRACT:
A loudspeaker is disclosed in which an enclosure is provided with a horn. A driver and vent are provided in side walls of the horn, spaced from a central axis of the horn. The vent is aligned so that when the central axis of the horn is horizontal and a central axis of said vent does not lie in a vertical plane containing the central axis of the horn, the central axis of the vent intersects the vertical plane containing the central axis of the horn. The driver, preferably a woofer, may also be aligned so that when the central axis of the horn is horizontal and a central axis of said driver does not lie in a vertical plane containing the central axis of the horn, the central axis of the driver intersects the vertical plane containing the central axis of the horn. The central axis of the vent and the central axis of the driver preferably intersect the central axis of the horn, more preferably intersect the central axis of the horn rearward of the mouth of the horn and most preferably intersect the central axis of the horn rearward of front edges of the vent and driver. The design merges the designs of a horn loudspeaker and bass reflex loudspeaker to arrive at a loudspeaker having some of the benefits of both designs.
