Abstract
An audio system includes a speaker having a transducer, where the speaker is positioned within an enclosure that forms a front volume and a rear volume on opposite sides of the transducer. The rear part of the enclosure defining the rear volume is formed of an acoustic metamaterial that defines a plurality of channels within the rear volume, where the number and dimensions of the channels is configured to virtual increase the rear volume to amplify a bass portion of sound produced by the speaker. In addition, the channels may be configured to match an impedance of the front volume to serve as an absorber for high frequency audio.
