Our Thoughts RADAR AI

A standout high-end standmount with real pedigree, but this asking price is very ambitious versus the used market. Against your database anchor, €3,500 sits well above the €1,041 75th percentile and far beyond the €475 median, so it does not read like a bargain. It is still below new-retail territory, but on used value alone it needs to be exceptionally clean and well-documented to justify itself.

What makes it worth chasing is the Duetto’s reputation for speed, scale, and vivid top-end detail in a compact footprint; it’s the kind of speaker that can sound more “big system” than its size suggests. If the pair is original, unmodified, and cosmetically strong, that helps. I’d still want proof of careful ownership, intact stands/boxes, and no driver or crossover issues, because at this price the upside is mainly in condition and completeness, not in finding a hidden deal.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Triangle Electroacoustique

Triangle Electroacoustique is a French loudspeaker manufacturer founded in 1980 by Renaud de Vergnettes, a Paris-based designer who abandoned a promising career in interior design to pursue his passion for high-fidelity sound. Beginning with prototype experiments in a garage, Vergnettes developed an innovative two-module speaker design featuring a decoupled woofer cabinet paired with a pyramid-shaped midrange and treble section. The company relocated to Soissons, where it has remained headquartered and maintained manufacturing operations for over four decades, establishing itself as one of France's most significant acoustic specialists.

Triangle's product portfolio centers exclusively on loudspeakers across multiple performance tiers. The brand became known for highly efficient drivers, horn-loaded tweeters, and a characteristically lively, dynamic sound signature that reflects French hi-fi aesthetics. Early models like the Minimum bookshelf speaker defined a generation of audiophile listening, while the company's reference-grade Magellan series—including the Concerto and Grand Concert models—demonstrated advanced technical expertise. Throughout its evolution, Triangle has maintained a commitment to hand-assembled construction and proprietary driver technology manufactured in-house.

Triangle occupies a distinctive position as a respected mid-to-high-end manufacturer with strong European credibility and growing international recognition. The brand appeals to discerning listeners seeking musically engaging speakers with distinctive character rather than clinical neutrality. Its longevity, commitment to French manufacturing, and consistent design philosophy have earned Triangle a devoted following among vintage audio enthusiasts and contemporary audiophiles alike, positioning it as a serious alternative to mainstream high-end brands while maintaining accessibility relative to ultra-premium segments.
