A headset speaker is provided in which a driver is provided in the dome of a speaker earcup and the dome has at least one vent aperture. The vent hole is closed by a movable closure having a corresponding opening therein that permits the size of the opening into the dome to be logarithmically varied between a fully open and fully closed position. A Thuras tube tuned to enhance bass frequencies is provided extending between the driver side and rear of the earcup. An opening to the Thuras tube remains fully closed by the movable closure unless the cup vent aperture is fully closed at which time the Thuras tube is opened.
