De hk-ts11 is geweldige sub woofer met mooie vol bass. De kast is glanzend zwart vandaar de weerspiegeling op de foto's maar het gaat om het geluid.
This is a solid buy if it’s clean and working: €90 sits below the kinds of used asking prices I found for the SUB-TS11, which were around €139,50 to €179,99, so it reads as a bargain rather than a fair-market ask. That makes it especially attractive if the cabinet, driver, and amp are intact.
The SUB-TS11 is a compact active sub with 200 W and a 25 Hz lower limit, so it’s a credible bass upgrade for a matching HK set or any modest stereo/home-theater rig. The main thing to check is basic functionality: power-up, no amp hum, and that the auto/on switch behavior is normal, because older powered subs can be simple bargains until a tired plate amp shows up.

Harman Kardon traces its origins to 1953, when Dr. Sidney Harman and Bernard Kardon, both engineers frustrated with conservative audio manufacturing at the David Bogen Company, invested $5,000 each to launch their venture in Westbury, New York. Their debut product, the Festival D1000, became the world's first compact AM/FM hi-fi receiver, blending breakthrough technology with sleek design to make high-fidelity sound accessible beyond technical enthusiasts. Pioneering innovations like the 1958 Festival TA230 stereo receiver, the 1959 Citation II ultra-wide bandwidth tube amplifier, and the 1970 CAD5 hi-fi cassette recorder with Dolby noise reduction cemented their legacy in simplifying premium audio for the home.
The brand focuses on integrated receivers, amplifiers, tuners, and speakers that emphasize performance, reliability, and elegant industrial design. Over decades, it expanded into home theater systems and automotive audio, powering systems in vehicles from Land Rover and BMW to Volvo and Polestar. While not delving into turntables, DACs, headphones, or cables, Harman Kardon prioritizes cohesive hi-fi components that deliver warm, detailed sound without unnecessary complexity.
Harman Kardon holds a solid mid-tier position in the hi-fi market, renowned among knowledgeable buyers for its enduring quality and value rather than ultra-high-end exotica or vintage collector status. Now part of Harman International, it appeals to discerning listeners seeking dependable, stylish gear that echoes its innovative heritage without commanding boutique premiums.
