This one lands right on the money for timing: the RBX-500 is an older, discontinued all-in-one from Onkyo’s iLunar era, so condition matters more than generation hype, and €50 is squarely at the market median rather than a premium. With only two recent comparables and both sitting at €50, this is a fair ask, not a bargain — but it’s also not overpriced.
What makes it worth considering is the unusual 2.1, 360-degree style presentation and the compact, conversation-piece design that still gives a satisfying room-filling sound when it’s healthy. At this price and in excellent condition, the upside is a clean, low-risk buy for someone who wants the look and convenience as much as the sound. Just make sure the Bluetooth pairs properly, the dock/input functions work if you’ll use them, and there’s no low-end rattle from age.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Onkyo traces its roots to postwar Japan, founded in 1946 in Osaka by Takeshi Goda, an engineer at Matsushita Electric who envisioned high-quality Japanese loudspeakers. Initially established as Osaka Denki Onkyo K.K., the company began production in 1948 with the acclaimed ED-100 speaker featuring a 25 cm driver, quickly building a reputation through LP concerts and innovative designs that resonated with audiophiles.
The brand excels in premium home audio, renowned for AV receivers, hi-fi amplifiers, and surround sound speakers that deliver exceptional clarity and power. Its portfolio spans turntables, DACs, headphones, and cables, bolstered by acquisitions like Pioneer's home electronics division in 2015, enabling cutting-edge integrations such as internet radio and high-resolution streaming.
Onkyo holds a solid mid-tier position in the hi-fi market, prized by discerning buyers for reliable performance and value rather than ultra-high-end exotica. Despite bankruptcy challenges in the late 2010s, its revival under new ownership preserves a legacy of technological innovation and pure sound enjoyment, appealing to both vintage enthusiasts and modern home cinema setups.
