THE HISTORY OF INFINITY
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. The company's first product was the Servo-Static speaker system which, as the name implies, consisted of electrostatic main panels and a revolutionary servo-controlled woofer based on the bomb guidance systems Nudell was developing at the time for defense contractor Litton.
In the late 1970s Infinity introduced the EMIT (electromagnetic induction tweeter) and EMIM (electromagnetic induction midrange) drivers. These were flat quasi-ribbons that worked to move air based on the principle of electromagnetic induction. The system used samarium–cobalt magnets, allowing for a very low ribbon driver mass-per-unit area. Variants were made, such as the EMIT-R (radial emit), the S-EMIT (super emit) and the L-EMIM (large emim). The IRS (Infinity Reference System) was an ultra-high end system, selling at $65,000 in the 1980s. It consisted of 76 EMIT tweeters, 24 EMIM midrange drivers, and twelve 12-inch polypropylene woofers in four towers. The Reference, and later Kappa series, were discontinued when Nudell sold Infinity to Harman Kardon.
Nudell left to form Genesis Technologies, a high-end loudspeaker company, founded in Seattle in 1991. Genesis' original flagship system, the 1.2, retailed for $235,000, and is basically an updated Infinity IRS system.
