Infinite Baffle

A type of speaker enclosure which essentially forgoes the enclosure by using only a baffle or front panel onto which the speaker drivers are connected. Infinite baffle designs do not make use of sealed enclosures or ports. These designs are seen primarily in car audio systems where speakers are often installed in the back dash below the rear window with no enclosure; their backs open to the trunk.
