Angeboten wird „Kappa 90“ von Infinity als Gebrauchtgerät aus der Kategorie „Standlautsprecher“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 9456583863 endet am 29.09.2026 um 13:57 Uhr.
Conditioned as good, this is basically at the median for the recent EUR market: €800 versus a €780 median, and just above the €797 75th percentile, so it reads as fair rather than cheap. I wouldn’t call it a bargain, but it’s close enough to normal pricing that the condition note matters more than the last €20 either way.
What makes it worthwhile is the Kappa 7.w’s reputation as a serious Infinity sub: it’s the kind of older, high-output piece buyers chase when they want weight and scale rather than polite modern compactness. If it’s genuinely clean and fully functional, the upside is in getting a respected, hard-to-find sub at a sensible ask; at this price, I’d mainly verify driver/suspension health and that any needed amp or hookup bits are present.
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.
