I am selling my quadral quintas 6650 home-cinema speaker set, consisting of: 2 × quintas 6650 floorstanding front speakers 1 × matching centre speaker 2 × matching surround speakers it is a 5.0 Set wi
Compared with a generic new interconnect at €200, this looks hard to justify for a clearly identified used cable unless it’s a premium, heavily documented bundle. The market evidence I can verify is thin for this exact model, so the price is difficult to benchmark tightly; at that point, the asking figure feels more like “top-end used cable money” than an obvious bargain.
What makes it interesting is that Quadral’s Quintas line is a mainstream home-cinema series with decent brand recognition, so a clean, original set can still appeal to someone matching gear or replacing a missing lead. The upside here is really completeness and condition: if the cable is genuinely high quality, correctly terminated, and visually clean, it’s worth considering—but at €200, I’d want proof of what’s included and why it’s priced above a simple replacement-level part.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Quadral emerged from Hanover, Germany in 1972 as the consumer audio division of the All Group, initially operating under the name all-akustik before adopting the Quadral brand in the late 1970s. The company's international breakthrough came with the introduction of the TITAN loudspeaker in 1981, establishing Quadral as a serious contender in premium audio. Today, Quadral operates under the ownership of Loxone, acquired in 2020, which has positioned the brand at the intersection of high-fidelity audio and intelligent building automation.
Quadral has built its reputation primarily as a loudspeaker manufacturer, with particular acclaim for its ribbon tweeters and flagship Aurum series. The company's engineering approach emphasizes clarity, tonal balance, and sophisticated acoustic design—hallmarks that quickly elevated the brand to the upper echelon of the hi-fi world upon its launch. Production of key components, including the renowned Aurum ribbon tweeters, remains based in Hanover, underscoring the brand's commitment to German manufacturing standards.
Quadral occupies the high-end to upper-midrange segment of the consumer audio market, positioning itself alongside other respected German speaker specialists. The brand appeals to discerning listeners who prioritize acoustic performance and engineering heritage over mass-market accessibility. With over five decades of experience and a track record of consistent quality, Quadral maintains credibility among serious audiophiles and collectors, though it remains less widely recognized than some larger international competitors.
