About Infinity

The history of Infinity as a speaker brand is a tale of passion, innovation, and a relentless pursuit of audio excellence. Founded in 1968 by Arnie Nudell, Cary Christie, and John Ulrick, Infinity quickly established itself as a frontrunner in the audio industry.

One of Infinity’s earliest breakthroughs was the introduction of the patented EMIT (Electromagnetic Induction Tweeter) technology. This innovative design revolutionized high-frequency reproduction by employing a flat diaphragm driven by electromagnetic induction. The EMIT tweeter became a signature feature of Infinity speakers and garnered widespread acclaim for its exceptional clarity and accuracy.

Infinity’s success eventually led to its acquisition by Harman International Industries in 1983. Under Harman’s stewardship, Infinity continued to thrive, pushing the boundaries of speaker technology with each new generation of products.
