Offered is „Concentro S 509 - Schwarz-HG“ by Elac as exhibit from the category „Standing Speaker“ on audio-markt.de - the online market place for high-end. The advert with the number 7973319990 ends on 30.10.2026 at 06:17 o'clock.
Elac’s Concentro sits at the top of the brand’s floorstander range, so this is a serious statement speaker rather than a generic used listing. At €9,490, it lands above the €7,996 median but still below the €10,247 75th percentile, so this reads as slightly firm but still fair rather than expensive.
That makes it a credible buy if the pair is complete and cosmetically tidy. The appeal here is obvious: big-scale dynamics, deep bass authority, and the sort of refined imaging and cabinet engineering that made the model stand out in the first place. In good condition, the main upside is getting a high-end flagship speaker for less than the upper quartile, with limited downside if it’s been well cared for and includes the original grilles, spikes, and packaging.
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.
