ABSTRACT:
A speaker and horn array having improved audio characteristics is formed in a baffle case. A plurality of small speakers are mounted in the baffle case in a vertical array in close proximity with one another. Each of the speakers has an acoustic baffle over the back of the speaker with an opening located in the baffle. An array of small horns are located in association with the speakers in the baffle case. As with the speakers the horns are also in a vertical array. Each of the horns includes an individual throat, however, all of the horns are joined into a common vertically oriented mouth. The throat of each horn is connected to the opening in the baffle of one of the speakers. This backloads the individual speakers with the common mouth of each of the horns resulting in common backloading of each of the speakers.
