Abstract
An acoustic waveguide in accordance with one or more embodiments of the present technology that comprises a housing having a proximal end with an inlet aperture and a distal end with an outlet aperture, and a mounting flange positioned at the proximal end and configured to acoustically couple a driver to inlet aperture. A plurality of sound channels extend through the housing and acoustically couple the inlet aperture to the outlet aperture. Each sound channel at least partially defining a sound path has an acoustic length, wherein at least one of the sound paths of the plurality of sound channels has a bend angle that exceeds 180 degrees.
