One or two thermally conductive chimney tubes extend through a loudspeaker cabinet that encloses a volume of air heated by a speaker driver. The open ends of each chimney are outside the cabinet. A column of air within each chimney is in contact with the external ambient air, but sealed off from the enclosed volume of air. As the speaker driver heats the enclosed volume of air, the material of the chimney transfers the heat to the column of air, which rises and carries the heat away into the external ambient air, cooling the inside of the loudspeaker cabinet and thus cooling the speaker driver. A second chimney can be oriented perpendicular to the first, ensuring that one of them is vertical regardless of cabinet orientation. A single chimney can be oriented diagonally, ensuring some chimney effect regardless of cabinet orientation.
