Aangeboden: een fantastisch klinkende set infinity sm-65 studio monitor series boekenplankluidsprekers. Deze compacte krachtpatsers uit de jaren '90 staan bekend om hun hoge rendement, heldere
€100 is a solid buy for these; typical used pricing I’m seeing lands roughly around €120–€170, with stronger examples and bundled stands pushing higher, so this sits a bit below the usual middle of the market. That makes it a good-value ask rather than a bargain-bin score, but still clearly attractive for a working pair.
What makes them worth a look is the classic Infinity sound: lively, efficient, and capable of a big presentation for a compact vintage box, which is why they keep moving in the used market. If the drivers are original and both cabinets are clean, this is the kind of older hi-fi buy that can punch above its price; just confirm both speakers play evenly, the foam/surrounds are intact, and any stands or grilles are included if shown, since those add real value on this model.

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.
