Infinity (audio)

Infinity is a manufacturer of loudspeakers.

Founded in 1968, Infinity has produced affordable home and mobile/car audio solutions by innovating materials used in loudspeaker production, such as neodymium magnets, and polypropylene cone and surround materials. A designer named Arnie Nudell was responsible for loudspeakers that incorporated the EMIT/EMIM ribbon drivers. These were flat (planar) quasi-ribbons that worked to move air based on the principal of electro magnetic repulsion. EMIT/EMIM were acronyms for Electromagnetic Induction Tweeter and Midrange. Variants were made, such as the EMIT-R or radial tweeter, and the SEMIT or super emit. The first high end Infinity speakers were the servo-static (using a servo to control the woofer movement) and the quantum. The massive Infinity-IRS (Infinity reference system) was considered the first ultra-high end system at a cost of $65,000 in the 1980's. it consisted of 76 EMIT tweeters, 36 EMIM midrange drivers, and twelve 12" polypropylene woofers in four towers. The reference and later Kappa series were discontinued when Mr. Nudell sold Infinity to Harman Kardon and left the company to form Genesis Technologies; a high-end loudspeaker company. The Genesis flagship system, in excess of $130,000 is basically an updated Infinity IRS system. Since the departure of Nudell, Infinity speaker designs have taken a simpler, and more conventional approach without planar drivers. 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 represented a popular consumer niche.

Today, Infinity produces packages for a wide range of audio applications, including multichannel surround sound home theatre packages, in-wall home speakers, marine applications, as well as beyond loudspeakers alone with the inclusion of powered sub woofers and car audio amplifiers.

Infinity products are used with all Hyundai-Kia Automotive Group's vehicles, some Mitsubishi vehicles in 90's to 2006 , and have also been a popular fixture in many Chrysler vehicles, manufacturing premium components for the company's top of the line audio systems found in their vehicles since roughly the 1980s.

It is part of the Harman International Industries group.
