Is €165 the kind of number that makes sense for these? For a used Infinity floorstander of this era, that’s generally a fair-to-good ask rather than a steal, assuming the pair is complete and working properly. It’s not so low that you should expect a gamble, but it’s also not ambitious if the cabinets and drivers are in clean shape.
What makes them worth a look is the classic Infinity balance: lively top end, open soundstage, and enough scale to make them rewarding with proper placement and amplification. The main buyer upside is getting a big, capable speaker for modest money; the main thing to check is age-related driver and crossover health, since unknown condition matters more than with a newer speaker. If they’re all original, cosmetic condition is decent, and both channels play cleanly, this is a sensible buy.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Infinity emerged in 1968 from a Woodland Hills, California garage, founded by Arnie Nudell, John Ulrick, and Cary Christie. Driven by Nudell's passion for classical music and innovative engineering, the trio launched with the groundbreaking Servo-Statik speaker system, featuring electrostatic panels paired with a servo-controlled woofer derived from defense technology. This American brand quickly gained traction through pioneering materials like neodymium magnets, mylar diaphragms, and polypropylene cones, establishing a legacy of pushing audio boundaries before acquisitions by Electro Audio Dynamics in 1974 and Harman International in 1983.
The company has long focused on loudspeakers as its hallmark, from early electrostatic hybrids and the iconic Reference and Kappa series to later EMIT and EMIM drivers in the 1970s. While primarily a speaker specialist, Infinity has ventured into home and mobile audio, including amplifiers and systems under Harman ownership, now part of Samsung since 2017. Turntables, DACs, headphones, and cables remain outside its core expertise.
Positioned as a mid-tier powerhouse with high-end aspirations, Infinity commands respect among knowledgeable buyers for its vintage collector appeal and enduring innovations. Once a darling of audiophiles for transparency and dynamics, it now blends accessible performance with Harman reliability, appealing to those seeking proven heritage without boutique exclusivity.
