ABSTRACT:
A loudspeaker has a rectangular casing providing a frontal wall in which are mounted a plurality of speaker mechanisms responding to differing frequency ranges. The high frequency speaker is oriented so that the axis of radiation is inclined upwardly and to one side of the normal to the front wall. In the preferred embodiments a lower frequency speaker, such as a low and midfrequency speaker, is similarly oriented but to a slightly lesser angle of inclination. The front wall has a conically concave portion the axis of which is similarly inclined, to accommodate the lower frequency speaker, and the high frequency speaker is mounted on the conical wall portion. Some embodiments also have a separate low frequency speaker. Two such speakers are located, widely spaced laterally from each other, adjacent the wall of a room with the left hand speaker radiating to the right and the right one radiating to the left.
