The side wall defines an opening sized to retain a speaker, and the first chamber defines a first volume. The second chamber is adjacent the first chamber, and comprises an inner wall, a front wall, and a second portion of the back wall, and defining a second volume greater than the first volume. The second volume is fluidly coupled to the first volume via a first set of vents on the inner wall, the second volume is fluidly coupled to an ambient atmosphere via a second set of vents, and the inner wall comprises at least a portion of the side wall.
