LOUDSPEAKER SYSTEM WITH WIDE DISPERSION BAFFLE ABSTRACT OF THE DISCLOSURE A wide dispersion baffle for a vertically oriented loudspeaker includes a first semi-conical reflective sec- tion that is concave toward the speaker and has a semicir- cular rim positioned at the periphery of the speaker. It extends at an angle of about 45° to the radiation axis of the speaker to its apex on the speaker axis. A second semi-conical reflective section is convex toward the speaker and extends from the apex of the first semi- conical section at substantially the same 45° angle with respect to the speaker radiation axis. Sound emanating from the vertically directed speaker is reflected by both the concave and convex semi-conical reflector sections in a pattern centered about a substantially horizontal plane, but the sound is reflected through widely diverging angles in such horizontal plane. Baffle arrangements can provide horizontal dispersion patterns of any angular width be- tween about 180° and 360°.
