Abstract
Opposed side walls of a loudspeaker horn are constructed to direct portions of a sound beam toward a target over different preselected included angles, producing an incident beam which is substantially coextensive with the target. The side walls preferably extend downstream at the preselected angles over a distance at least comparable to a maximum wavelength at which the horn is to be used.
