ABSTRACT:
A woofer system for an automotive audio system is provided with a protective cover extending over a section of a vehicle panel which both forms part of a vehicle body and serves as a speaker diaphragm producing acoustic vibrations at audio frequencies. The cover is in a spaced-apart relationship with said section so as not to interfere with oscillation of the section of the vehicle panel while it is oscillating at audio frequencies. The cover has a support extending toward the vehicle panel and surrounding the section. The support is formed with at least one opening for transmitting acoustic vibrations produced by oscillation of the section of the vehicle panel.
