Merk : infinity model : bu-80 aansluiting: bedraad technische specificaties: configuratie: één subwoofer vermogen van de geïntegreerde eindversterker: 110 w (rms) frequentiebereik: 35 hz - 150 hz (+/-
Timing doesn’t really hurt this one: the BU-80 is an older, discontinued Infinity powered sub, but it’s still a credible budget piece if you want simple home-theater bass without spending much. At €139, it sits in the fair-to-slightly-strong zone versus typical used examples I’d expect around €55–€130, so this is not a steal, but it is a reasonable ask if the unit is clean and fully working.
What makes it worthwhile is that it’s a compact 8-inch, 75W class sub with usable low-end extension for small rooms and modest systems, plus the Infinity name still carries decent goodwill among vintage-budget buyers. The upside is best when the amp is quiet, the driver is original, and the controls are smooth; because these are older powered subs, the main thing to verify is that the plate amp, output, and auto-on behavior are all solid before paying near the top of the range.
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.
