Offered is „UNO XD“ by Avantgarde Acoustic 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 221311600 ends on 08.12.2026 at 15:02 o'clock.
The timing matters: the UNO XD was a 2015–2022 generation, so this is a mature design rather than a current model. At €12,900, though, it sits below your comparable-market 25th percentile of €12,995 and well under the €13,172 median—an unusually strong buy if the pair is complete and fully working.
These remain compelling high-efficiency horn speakers: the direct, dynamic midrange and treble pair with a DSP-controlled active bass section that can be adjusted to suit the room. They are also unusually easy to drive, making low-powered valve amplifiers a realistic option. For a product of this class, the price leaves little room for complaint; simply confirm both bass amplifiers, DSP controls, inputs, and calibration/service accessories are present and operating correctly.
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.
