Infinity Systems is an American manufacturer of loudspeakers founded in Los Angeles in 1968 and headquartered in Stamford, Connecticut.

Founded in 1968 by Arnie Nudell, John Ulrick and Cary Christie, Infinity has produced home and mobile audio products by employing innovative materials such as neodymium magnets, mylar diaphragms, and polypropylene cones.

It consisted of 72 EMIT tweeters, 24 EMIM midrange drivers, and twelve 12-inch polypropylene woofers in four towers.

Nudell left to form Genesis Technologies, a high-end loudspeaker company, founded in Seattle in 1991.

While not as elaborate or high end as previous Infinity efforts, they filled a popular consumer niche.
