Abstract
An acoustic waveguide includes a plurality of projections to redirect sound waves to obtain a desired wave front, such as a flat plane wave front or an asymmetric curved wave front. The waveguide includes two waveguide members that are mirror images of each other. The waveguide members have corresponding vanes and projections. The waveguide includes an essentially circular input opening for alignment with a compression driver and provides a substantially rectangular output opening from the waveguide.
