Abstract
A loudspeaker horn includes a pair of opposed flared sides defining a passage diverging to a mouth, and a vane positioned in the passage for steering sound waves through the passage. The vane may have a straight configuration and be either centrally located between the flared sides or laterally offset in the diverging passage. The vane may be fixed in position or, more preferably, be pivotable so as to be adjustable before each new use according to conditions at that use. The horn may be part of a horn unit that includes a funnel for feeding sound to the horn, and the horn or horn unit may be part of a horn loudspeaker.
