1. An acoustic waveguide, comprising:
a housing having a proximal end with an inlet aperture, a distal end with an outlet aperture, and a depth from the proximal end to the distal end;
a mounting flange positioned at the proximal end and configured to acoustically couple a driver to the inlet aperture; and
a plurality of sound channels extending through the housing and acoustically coupling the inlet aperture to the outlet aperture, each sound channel having—
a bend area at an intermediate position along the sound channel, and
a flare portion downstream of the bend area and extending from the bend area to the outlet aperture, wherein the flare portion extends along approximately 49%-69% of the depth of the housing.
