Abstract of the Disclosure A loudspeaker horn has a throat section with a rectangular cross-section to which the driver unit is coupled. The throat section has side walls joined together by substantially flat digressing top and bottom walls. The horn has a square mouth which is formed by flat walls forming a bell section which runs between the throat section and the mouth with an angular digression corresponding to the desired horn dispersion pattern, this square mouth assuring equal low frequency directivity control both horizontally and vertically. A pair of the walls may be additionally flared outwardly at a portion thereof near the mouth to provide improved midrange directivity control. The use of planar sides between the throat section and the mouth makes for an improved directivity pattern.
