Abstract: Embodiments are described for a high-frequency waveguide that improves the performance of large-scale surround sound and immersive audio environments. A horn waveguide is configured to be asymmetric about one of a vertical axis and horizontal axis of the waveguide to form an asymmetric horn waveguide. A spherical enclosure surrounds the asymmetric horn waveguide to form a horn speaker, and a three-axis mounting system is configured to fix the horn speaker to one of a wall or ceiling surface of the venue, wherein the mounting system facilitates rotating the horn speaker to a location that provides maximum coverage of the venue within the passband of the asymmetric horn waveguide.

Abstract: In one embodiment, there is provided an asymmetrical acoustic horn. The asymmetrical acoustic horn includes a single acoustic waveguide. The single acoustic waveguide includes a first asymmetrical horn section configured to support one or more first acoustic transducers, and a second asymmetrical horn section configured to support one or more second acoustic transducers, the one or more second acoustic transducers having a different frequency range than the one or more first acoustic transducers. The first asymmetrical horn section and the second asymmetrical horn section are contiguous with each other and are configured to separate respective ones of the one or more first acoustic transducers from corresponding ones of the one or more second acoustic transducers by a corresponding one or more predetermined and fixed distances.
