A sound reproduction system is disclosed in which a sound barrier defines a horn passageway having an upstream and a downstream section. A driver is mounted at the throat of the upstream section so that its rearward directed output communicates with the downstream section. Output from the upstream section and the rearward directed output of the driver are merged at a tap point located at the beginning of the downstream section. By altering the respective areas and lengths of the upstream and downstream sections a variety of different frequency dependent responses are obtained. In one example, low-frequency response systems of heretofore unobtainable compact size are realized. |
