Abstract
An improved system and method for reducing standing waves and diffracted waves in speaker a driver enclosure is disclosed. The speaker driver enclosure has an interior enclosure surface, shaped such that any cross section taken of it comprises a looped, substantially continuously curved, non-rational B spline. A rear enclosure surface is provided, the rear enclosure surface being shaped substantially the same as the interior enclosure surface and offset from the interior enclosure by a wall thickness. An outer baffle surface has slightly varying curvatures such that substantially any cross section taken of it comprises a continuously curved, non-rational B spline and a flat surface shaped such that at least one loudspeaker driver may be mounted to it. A loudspeaker driver is mounted to the flat surface. The enclosure may include a rounded edge surface, whereby substantially every cross section taken along it has a slightly different continuously curved, non-rational B spline, such that a line tangent to it does not intersect the flat surface.
