Har tillslut valt att sälja dessa Kappa 90. Alla 4 basar är omkantade för några år sedan. Toppen på ena högtalaren har en spricka, som inte påverkar något, men som är vanligt på dessa.
This one is well inside the sweet spot for the market: at kr 5,500, it sits below the kr 6,628 median and comfortably under the kr 8,398 75th percentile, so it reads as a solid buy rather than an ambitious ask. Against the kr 4,600 25th percentile, it’s not a screaming bargain, but it is priced attractively for a desirable piece of older bass hardware.
The Kappa line is respected for deep, authoritative low end and high output, and these subs can still be very satisfying if the driver is healthy and the cabinet is intact. Because the listing says condition unknown, I’d mainly want confirmation on voice-coil cleanliness, surround condition, and whether any original grille or hardware is included; if it’s mechanically sound, this is the kind of vintage sub that can punch above its price.
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.
