Infinity 1500 speakers. Classic Vintage. HI-FI Stereo. Fully revitalised.
Infinity Systems was founded in 1968 by a physicist Arnold Nudell, audiophile Cary Christie, and electronics engineer John Ulrick in Chatsworth (California). Nudell and Ulrick, who co-created the laser distance meter at Litton, thought that a servo system for aiming a laser beam at a target could be adapted to control a high quality subwoofer. This is how the company’s first product, i.e. the 3-way electrostatic loudspeaker Servo Static, was created, and Infinity earned the reputation of a technological innovator. In the 70s, further innovative solutions were introduced, such as: EMIT (Electromagnetic Induction Tweeter) tweeter, polypropylene speaker membrane or breakthrough EMIM (Electromagnetic Induction Midrange) technology. The company used most of these innovations in 1980 in the IRS (Infinity Reference Standard) speaker which was almost immediately hailed as one of the best-sounding speakers ever made and a “must have” product in almost every audiophile magazine in the world. In 1982, the company also began producing car speakers and was taken over by the Harman International Company group. Despite the takeover, the Infinity brand is still synonymous with the highest quality of sound based on the latest technological solutions.
The Infinity 1500 are loudspeakers from the early 80s definitely distinguished by high selectivity, strong bass and beautiful, soft treble. This model fully reflects the obsession of the company’s founders in finding the way to play music in a way that provides the listener with maximum pleasure.
Old coatings have been removed and then the set was painted using the automotive wet painting technique. White varnish was used and secured with transparent matt.
