An assembly for use in a designated listening area includes a body having a frame rail supporting or framing the body laterally adjacent to the designated listening area, and defining a cavity, and a subwoofer assembly having subwoofer speakers each defining a smaller second air volume. The subwoofer assembly is mounted to the frame rail such that the second air volumes are contiguous with and open into the first air volume. A sealing mechanism enclosed the first air volume within the cavity. A method includes providing a subwoofer assembly having subwoofer speakers defining respective second air volumes, mounting the subwoofer assembly to a frame rail laterally adjacent to the designated listening area such that the respective second air volumes are contiguous with and open into the first air volume, and sealing the first air volume with a sealing mechanism.

Frame rail-integrated subwoofer assembly and method

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.
