Abstract
A loudspeaker system is described that includes passive radiators in opposite side panels adjacent to and on either side of a front panel speaker driver. A first front partition within the enclosure is attached to the enclosure at a first attachment point between the speaker driver and the first passive radiator and extends into the enclosure at an angle from the front panel. A second front partition within the enclosure is attached to the enclosure at a second attachment point between the speaker driver and the second passive radiator and also extends into the enclosure at an angle from the front panel.

15. A loudspeaker system comprising:
-
a rectangular enclosure having front, rear, side, top, and bottom panels; a speaker driver attached to the front panel to drive sound; first and second passive radiators on side panels adjacent to the front panel; a first partition within the enclosure extending from a side panel between the speaker driver and the first passive radiator toward the center of the enclosure; a second partition within the enclosure extending from a second opposite side panel between the speaker driver and the second passive radiator toward the center of the enclosure, the first and second partitions being angled from the front panel at an angle of about 45 degrees and extending into the center of the enclosure so that the distance between the ends of the first and second partitions is about one half the distance between the two respective side panels; and third and fourth partitions extending from respective opposite side panels and angled at about 45 degrees from the rear panel such that sound waves from the rear of the speaker driver are compressed by the first and second partitions, expanded into the center of the enclosure and compressed again by the third and fourth partitions upon approaching the rear panel. - View Dependent Claims (16)

17. A loudspeaker system comprising:
-
a front panel and a rear panel; first and second parallel planar side panels between and attaching the front and rear panels; a speaker driver mounted to the front panel; a first passive radiator mounted to the first side panel; a second passive radiator mounted to the second side panel; a first partition mounted to the enclosure between the speaker driver and the first passive radiator and extending toward the center of the enclosure behind the speaker driver; a second partition mounted to the enclosure between the speaker driver and the second passive radiator and extending toward the center of the enclosure and the first partition behind the speaker driver, wherein the distance between the ends of the first and the second partition at the center of the enclosure behind the speaker driver is about one half the distance between the two respective side panels; and a third partition mounted to the enclosure between the rear panel and the first passive radiator and extending toward the center of the enclosure behind the speaker driver; and a fourth partition mounted to the enclosure between the rear panel and the second passive radiator and extending toward the center of the enclosure and the first partition behind the speaker driver. - View Dependent Claims (18, 19, 20)
