Is €9,999 a realistic price for a pair of Piega Coax 811s, or is this a single-unit listing masquerading as a pair? Based on your database median of €767 for comparable listings, this asking price is wildly ambitious, sitting more than five times above the 75th percentile of €1,750 and vastly exceeding new single-unit prices of €13,450. If this is indeed a single speaker, the price is nonsensical; if it is a pair in the €9,999 range, it would be an unbelievable bargain given new pair prices range from €26,900 to €29,500.
Assuming the listing is a genuine pair at €9,999, this is a massive buying opportunity for the Coax 811, a flagship floorstander renowned for its UHQD drivers and 22 Hz–50 kHz bandwidth. The aluminum-silver finish adds rarity, and owning these at roughly 35% of new pair cost offers immense upside for enthusiasts seeking high-end German engineering without the full retail premium. However, verify immediately whether €9,999 covers one speaker or the pair, as that distinction completely flips the verdict from a scam to a legendary deal.
