Abstract: A product is disclosed that may be used in a vehicle and may include a subwoofer speaker driver mounted in an enclosure which is attached to the vehicle's body. A volume of space may define an acoustic chamber in a closure of the vehicle. A duct may be provided between the enclosure and the acoustic chamber. The size of the enclosure may be minimized by using available space in the closure to serve as part of the bass chamber volume for the subwoofer.
