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 5870961802 ends on 10.11.2026 at 10:31 o'clock.
This looks fair to slightly attractive at €29,990: it sits essentially on top of the €29,936 median and just above the €29,984 75th percentile, so it’s not a bargain, but it is right in the normal market band.
That makes it a sensible buy if the speakers are clean, complete, and have been stored well. The UNO SD is well liked for big, effortless scale, very low distortion, and the kind of dynamic ease that smaller boxes can’t match. At this level, the real upside is condition and provenance: original packaging, factory accessories, and a careful owner matter more than squeezing a few hundred euros off.
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.
