ABSTRACT:
A loudspeaker installation for the rear shelf of a motor vehicle. A lightweight, ribbed loudspeaker enclosure is fastened to the underside of the rear shelf so as to be suspended into the trunk of the vehicle and disposed about a conventional loudspeaker flush-mounted to the rear shelf. The enclosure acoustically isolates the vehicle passenger compartment from the trunk, and a duct disposed within the enclosure communicates with the passenger compartment to enhance the low frequency audio response of the installation.
