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. Infinity had an ownership relationship with Eastern Air Devices, later known as EAD. This involved the consumer brand of KLH speakers, and Avid< Perrless drivers, and Kyocera/Cybernet (which produces electronics) 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. Genesis' original flagship system, the 1.2, retailed for US$235,000, and is basically an updated Infinity IRS system. Since the departure of Nudell, Infinity speaker designs have taken a more mass market-oriented approach. The efficient SM (Studio Monitor) series incorporated a polycell tweeter and graphite-impregnated midrange/woofers. While not as elaborate or high end as previous Infinity efforts, they filled a popular consumer niche. == References ==
