1. A playback device comprising:
- an electroacoustic transducer; and
a housing comprising an acoustic waveguide configured to provide an acoustic path between the electroacoustic transducer and an opening of the housing extending around an axis passing through the electroacoustic transducer, wherein the acoustic path length varies less than about 10% as a function of azimuthal angle about the axis passing through the electroacoustic transducer.

Abstract
A playback device comprises an electroacoustic transducer; an acoustic waveguide in fluid communication with the transducer; and a housing delimiting an opening of the waveguide, the opening extending around an axis passing through the transducer. The opening may have a radial distance from the axis that varies with an azimuthal angle about the axis. An acoustic path length within the waveguide, between the transducer and the opening, is substantially constant and independent of azimuthal angle about the axis.
