A waveguide for conducting sound that is generated by a loudspeaker that is acoustically coupled to the waveguide. There is a duct with an external wall, an interior opening circumscribed by the wall, and an outlet, and an air-adsorbent structure coupled to an inside of the external wall of the duct such that the air adsorbent structure lines at least a portion of the wall. The apparent volume ratio of the air adsorbent structure is at least about 1.5.
