Technical Examples

A sound system is provided that groups a midrange horn with a high frequency ("H") horn. The sound system includes an HF horn coaxially coupled to a midrange horn, and two HF drivers aligned edge-to-edge. The sound system further includes two midrange drivers aligned edge-to-edge and coupled to the midrange horn. The edge-to-edge alignment of the two HF drivers is substantially perpendicular to the edge-to-edge alignment of the two midrange drivers. A method for grouping a plurality of midrange drivers and a plurality of high frequency drivers is also provided. This configuration may produce increased sound pressure levels while minimizing acoustic crossover interference problems.
