Offered is „Coax 511“ by Piega as second-hand device from the category „Standing Speaker“ on audio-markt.de - the online market place for high-end. The advert with the number 8035157913 ends on 16.12.2026 at 03:00 o'clock.
The Coax 511 is a notably slim, aluminium-bodied floorstander with Piega’s distinctive coaxial ribbon driver. At EUR 3,000 in good condition, it looks like a strong deal: your 73-listing sample puts the median at EUR 2,946, so this is essentially median pricing, while still far below the EUR 8,357 75th percentile. It is not a speculative bargain, but it is very fairly bought.
The attraction is a coherent, airy mid/treble presentation from the C111 coaxial ribbon, backed by genuinely deep bass from two active 160 mm woofers and two passive radiators. Sensitivity is a useful 90 dB, though the 4-ohm load deserves a capable amplifier. At 32 kg per speaker, check that both ribbon assemblies, woofers, grilles, terminals, and feet are intact; assuming they are, this is a worthwhile opportunity rather than a listing needing aggressive negotiation.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
PIEGA: Swiss Precision in High-End Loudspeakers
Founded in 1986 by loudspeaker pioneer Kurt Scheuch and salesman Leo Greiner, PIEGA emerged from modest beginnings in a garage before establishing itself as a serious player in premium audio engineering. Based in Horgen on Lake Zurich, the company has spent over three decades perfecting its craft, with the name itself derived from the Italian word "piegare"—to fold—reflecting the meticulous ribbon-folding process central to its manufacturing heritage. This Swiss foundation has become synonymous with uncompromising build quality and timeless design.
PIEGA specializes exclusively in loudspeakers, positioning itself as a pure-play speaker manufacturer rather than a diversified audio brand. The company's signature innovation is its proprietary ribbon technology, which serves as both midrange driver and tweeter in a coaxial configuration found nowhere else in the industry. These ribbons are handcrafted in-house using wafer-thin aluminum foil, representing the technical cornerstone that distinguishes PIEGA's sonic character and manufacturing philosophy.
The brand occupies the ultra-premium segment of the high-end market, with flagship models commanding prices exceeding 195,000 Swiss francs. PIEGA appeals to discerning audiophiles and collectors who prioritize Swiss engineering excellence, proprietary driver technology, and meticulous craftsmanship over mass-market accessibility. Its reputation rests on a successful balance between honoring traditional values and embracing continuous innovation—a positioning that has sustained its prestige across four decades of operation.
