Abstract
A high frequency horn for use in a multiple frequency loudspeaker system having a midrange transducer and a high frequency transducer is disclosed. The high frequency horn includes a horn chamber, horn mouth, a horn throat, a tuned resonant cavity, and a port connected to both the tuned resonant cavity and the horn chamber. The horn throat and horn chamber are located on opposite sides of the horn chamber, the port is located proximate to the horn throat, and the horn throat is configured to be connected to the high frequency transducer. The tuned resonant cavity is tuned to reduce high frequency standing waves produced by the midrange transducer within the horn chamber.
