Vintage Infinity speakers

Arnie Nudell, John Ulrick and Cary Christie founded Infinity in Los Angeles in 1968, and their first product was the Servo-Statik. In the late 1970s Infinity introduced the EMIT and EMIM, flat planar tweeters and midranges with a thin film diaphragm driven by induction, and it pushed polypropylene woofer cones as a step up from paper. The no-compromise IRS used 72 EMITs, 24 EMIMs and twelve 12-inch woofers in four towers, and the Reference Standard speakers of the early 1980s brought some of that to living rooms. The Kappa series later in the decade used an improved EMIT-K. Harman bought Infinity in the early 1980s. Many of these speakers are big towers with tweeters on the back as well as the front, and several are rated at 4 ohms or lower, so check every driver and your amplifier before you buy.
