Angeboten wird „K6 Signature - Proac“ von ProAC als Gebrauchtgerät aus der Kategorie „Standlautsprecher“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 5377654545 endet am 09.06.2026 um 00:35 Uhr.
The good condition keeps this from being a project, but at €17,850 it sits a bit above your recent used-market midpoint of €16,200 and also above the €17,086 75th percentile, so this is an ambitious but not crazy ask rather than a bargain. For a clean pair of K6 Signature speakers, I’d still call it plausible if the seller can show careful ownership and the cabinets, drivers, and finish are genuinely tidy.
This is a worthwhile buy because ProAc’s big floorstanders are usually valued for their scale, tonal richness, and easy musicality, with enough refinement to reward serious amplification and room matching. The upside here is mainly in condition and provenance: if they’re original, unmolested, and include the right accessories, that matters more than chasing the lowest price. At this level, I’d just confirm driver health, original grilles/spikes, and any service history before moving fast.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
ProAc stands for Professional Acoustics, a British loudspeaker manufacturer founded in 1979 by Stewart Tyler. The brand emerged from Tyler's earlier venture, Celef Audio, which he established in 1973 to develop compact speakers with extended bass response and refined treble. Based in Borehamwood, Hertfordshire, ProAc was formally launched after Tyler discovered superior drive units manufactured by ATC, which prompted him to establish a dedicated brand for higher-quality designs. The company relocated to a dedicated factory in Brackley in 1990, where production continues today. Despite Tyler's passing in 2021, ProAc remains a family-run operation committed to his original vision.
ProAc specializes exclusively in loudspeakers across multiple categories, from compact standmount designs to larger floor-standing models. The brand is recognized for its signature product lines, including the Tablette, Response, and K-Series ranges. Their standmount speakers, particularly the Response DB1 and its updated DB1R variant, have achieved particular acclaim for delivering performance that belies their compact dimensions. ProAc's design philosophy emphasizes bespoke drivers, high-quality crossovers, and carefully constructed cabinets engineered for natural sound reproduction.
ProAc occupies the premium segment of the hi-fi market, positioning itself as a high-end specialist rather than a mass-market manufacturer. The brand is known for refusing to compromise on quality, with Tyler famously stating that ProAc does not make cheap speakers or cheap sounds. This commitment to excellence at reasonable prices has earned ProAc a devoted following among audiophiles, sound engineers, and music producers worldwide, establishing it as a respected boutique manufacturer with over five decades of heritage in loudspeaker design.
