Quasi-stereo single woofer system

Abstract

A compact audio woofer arrangement for a motor vehicle includes an enclosure installed in the motor vehicle. The enclosure contains a woofer or subwoofer emitting a sound. The enclosure includes a primary and secondary through-hole. The primary through-hole allows the woofer to interface with the interior of the vehicle and provides sound directly from the enclosure into a passenger compartment at the primary location. A extended vent acting as an acoustic transmission line is coupled to the second through-hole. The vent transmits sound from the enclosure to a secondary location remote from the primary location, such that the sound is emitted into the adjacent passenger compartment. The primary and secondary acoustic outputs differ by physical location in the motor vehicle, and also by frequency response of the emitted sound, thereby emulating a quasi-stereo environment.
