A vibrating panel assembly configured to radiate sound into a passenger compartment of a vehicle having a support structure is provided. The assembly includes a substrate panel having front and back surfaces. The panel includes an inner portion, an outer boundary portion formed on the perimeter of the panel and an intermediate portion between the inner portion and the outer boundary portion. The vibrating panel has a frequency distribution of modes in a range of audible frequencies. The panel is configured to be attached to the support structure. An electroacoustic vibrator is mounted on the inner portion at the back surface at a predetermined location and is configured to vibrate the panel over the range of audible frequencies in response to an electrical signal. The intermediate portion is configured to increase modal density of the panel.
