Offered is „Concentro S 509“ by Elac 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 8199795042 ends on 25.12.2026 at 09:09 o'clock.
Good condition materially helps here: at €8,500, this sits exactly at the 75th percentile of nine recent comparable listings and above the €7,631 median. It is therefore a full-market asking price rather than a bargain, though not clearly overpriced; negotiation would be worthwhile if collection or delivery is inconvenient.
The Concentro remains a serious, desirable loudspeaker: its concentric VX/JET driver arrangement brings coherent imaging and focus, while the multiple aluminium-sandwich bass drivers deliver scale, deep bass, and substantial dynamic headroom. The cabinets are also imposing and highly engineered, making clean examples relatively special. Before committing, confirm the exact Concentro version, matching serials, undamaged drivers and finish, complete grilles/feet and any supplied accessories, plus safe delivery—these are exceptionally large and heavy speakers.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Elac, a cornerstone of German audio engineering, traces its origins to September 1, 1926, when Electroacustic GmbH was founded in Kiel by Dr. Heinrich Hecht, Dr. Wilhelm Rudolph, and Gerhard Schmidt. Initially focused on sonar technology and underwater acoustics for maritime applications, the company peaked at 5,000 employees during World War II, supplying the Kriegsmarine. Postwar restrictions pivoted it toward consumer goods like sewing machines and radios, while distributing brands such as Sony, Fisher, and Nakamichi in Germany. By 1978, it divested its nautical division to concentrate on hi-fi, with Austrian CEO Wolfgang John taking the helm in 1981 to steer its modern trajectory.
Elac excels primarily in loudspeakers, renowned for innovations like the 1985 4Pi omnidirectional tweeter and the JET folded-ribbon tweeter, which deliver exceptional dispersion and clarity. Its portfolio spans high-end floorstanders, bookshelves, and compact systems across series like Vela, Solano, and Debut, alongside turntables such as the Miracord lineup, subwoofers, and electronics including amplifiers and DACs. This broad yet speaker-centric range caters to discerning setups from entry-level to reference-grade.
Positioned as a high-end mainstay with mid-tier accessibility, Elac commands respect among audiophiles for its precise German engineering, balancing value and performance without chasing boutique exclusivity. Under John's enduring leadership, it sustains a reputation for dynamic, transparent sound that rivals elite competitors, appealing to knowledgeable buyers seeking timeless quality over fleeting trends.
