Abstract
In one embodiment, an asymmetric acoustic horn is provided. The asymmetric acoustic horn includes a single acoustic waveguide. The single acoustic waveguide includes a first asymmetric horn portion configured to support one or more first acoustic transducers, and a second asymmetric horn portion configured to support one or more second acoustic transducers having a different frequency range than the one or more first acoustic transducers. The first and second asymmetric horn portions are adjacent to each other and configured to separate each of the one or more first acoustic transducers from a corresponding acoustic transducer of the one or more second acoustic transducers by one or more corresponding predetermined and fixed distances.
