A low-profile panel assembly configured to provide sound having at least one acoustic wavelength within a passenger compartment of a vehicle is provided. The vehicle has a support structure. The assembly includes a substrate panel perforated with at least one sub-wavelength hole which extends between front and back surfaces of the panel. The panel is configured to be attached to the support structure. A continuous membrane of facing material overlies and is in contact with the panel. The membrane is tightly stretched over and covers the at least one hole at the front surface of the panel. An electroacoustic sound source is configured to radiate acoustic waves against the back surface of the panel. The radiated acoustic waves travel through the at least one membrane-covered hole to vibrate at least one portion of the membrane which tightly covers the at least one hole. The at least one vibrating portion of the membrane radiates acoustic waves into the passenger compartment of the vehicle.
