1. A playback device comprising:

  • 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 and having a radial distance from the axis that varies with an azimuthal angle about the axis,wherein an acoustic path length within the waveguide, between the transducer and the opening, is substantially constant and independent of azimuthal angle about the axis.
