An automotive interior trim panel includes a contoured panel having an interior surface forming a portion of a passenger compartment of a vehicle, and an exterior surface cooperating with an exterior body panel, such as a door, to define a first volume. A speaker port is formed in the contoured panel for locating a speaker within the first volume. A shell including an integral acoustic volume circumscribes a portion of the exterior surface of the contoured panel, including the speaker port. The shell is mounted to the exterior surface of the contoured panel so as to define an acoustic chamber supported by the contoured panel and extending within the first volume.
