Offered is „UNO SD iTRON“ by Avantgarde Acoustic as second-hand device from the category „Active Speaker“ on audio-markt.de - the online market place for high-end. The advert with the number 4799335445 ends on 30.10.2026 at 11:10 o'clock.
The UNO SD has long had a cult following for its effortless scale, dynamics, and horn-loaded immediacy, and €29,990 lands right on the upper end of the recent used market but still essentially at the 75th percentile, not beyond it. With a median at €29,826 and a 75th percentile at €29,990, this reads as fair-to-strong pricing rather than a bargain, but not an ambitious ask.
That makes it a sensible buy if the presentation is clean and the setup has been cared for, because this model rewards placement and can sound far larger and faster than most floorstanders. The real upside is getting a high-sensitivity, room-filling speaker that can run beautifully even with modest amplification; at this price, the key checks are cosmetic condition, driver health, and whether any original packing or accessories are included.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Avantgarde Acoustic was founded in 1991 by Holger Fromme and Matthias Ruff in the Odenwald region of Germany, near Darmstadt. The company's roots trace back to the mid-1980s when the two founders joined forces with a singular vision: to build the world's best loudspeakers. Fromme's passion for the brand stems from his youth, inspired by the overwhelming sonic power of open-air rock concerts featuring artists like Pink Floyd and Genesis—a dream he sought to recreate in the home listening environment. Today, Avantgarde Acoustic remains a handcrafted, German-manufactured operation, shipping its products to over 60 countries worldwide.
The brand specializes exclusively in horn loudspeakers and amplifiers, rejecting conventional speaker designs in favor of horn technology. Avantgarde's loudspeakers are engineered to deliver exceptionally low distortion through proprietary horn principles and original driver designs, complemented by the company's iTRON technology for precise diaphragm control. Their product range includes models such as the TRIO Classico and TRIO G3, representing decades of refinement in both acoustic performance and industrial design.
Avantgarde Acoustic occupies the ultra-premium, niche boutique segment of high-end audio. The brand commands significant respect among discerning audiophiles for its uncompromising engineering philosophy and handcrafted quality, though its distinctive horn aesthetic has historically met with mixed reception in mainstream American markets. Positioned as a luxury manufacturer for music enthusiasts willing to invest substantially in sonic excellence, Avantgarde represents a specialized, design-forward approach to speaker manufacturing that prioritizes acoustic purity and longevity over mass-market appeal.
