Abstract
A loudspeaker array has a cabinet in which is formed a continuously open circumferential horn for controlling sound produced by a number of transducers which are positioned in the cabinet, at a throat of the horn. The continuously open circumferential horn may 1) improve the power efficiency of the transducers without unwanted aliasing effects in audible frequency ranges and 2) provide vertical control for sound emitted by the transducers by flaring.
