Condition is unknown, so this listing has to be judged mainly on price, and on that score it looks very ambitious versus your recent EUR comps. At €11,800, it sits far above the €207 median and even above the €9,035 75th percentile, so this is not a normal used-market ask; it would need a very special setup, provenance, or extras to justify itself.
That said, the upside is that this is a serious open-baffle speaker from a brand people usually buy for scale, openness, and speed rather than boxy hi-fi polish. If the drivers, frames, and any crossover work are original and fully healthy, it could still be a compelling listen, but at this level I’d want clear proof of condition, completeness, and recent servicing before entertaining it as a buy.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
