Patent ID: 8014545

Claim:
A loudspeaker system comprising: a) an enclosure defining an interior region, the enclosure having an open end; b) a baffle coupled to the enclosure along a plane parallel with the open end, the baffle disposed at least partially within the interior region through the open end; wherein the enclosure and the baffle are substantially square-shaped, the baffle having an interior region defined by the first angled surface, the second angled surface, a first side, and a second side; c) at least one high-frequency speaker coupled to the baffle, the at least one high-frequency speaker operating in the 4 kHz to 10 kHz frequency range and oriented at an oblique angle with respect to the plane; and d) means for altering sound waves projected from the at least one high-frequency speaker coupled to the baffle comprising a three-dimensional ribbed portion defined by a plurality of ribs each having a peak region, the plurality of peak regions aligned to project a substantially concave arc along the ribbed portion away from the at least one high-frequency speaker, the plurality of ribs each having a substantially convex profile perpendicular to the path of sound waves projected from the at least one high-frequency speaker whereby sound waves projected from the at least one high-frequency speaker are altered by reflective, dispersive, absorptive or diffractive qualities of the three-dimensional ribbed portion to modify the spectral profile of the projected sound waves in the 4 kHz to 10 kHz frequency range, such that, when the loudspeaker system is mounted in a wall or ceiling, the loudspeaker projects a sound field, including sound waves in the 4 kHz to 10 kHz frequency range, that is substantially indistinguishable from the sound field of a loudspeaker located within the same listening plane as a listener.
