The Triangle Esprit Altea Ex originally retailed around AUD2,500 new, so at AUD699 used, this is a fair deal smack in the typical second-hand range of AUD700-1,200 for very good condition pairs—seen listings at AUD1,100 from reputable dealers and lower abroad equivalents converting to about AUD800-1,000. It's no steal given the model's age (discontinued over a decade ago), but solid value for its bass-reflex punch and easy 91dB sensitivity if the driver's intact.
Buyers should verify the bass drivers for surround degradation—common on these 6.5-inch units after heavy use—and check cabinets for port resonance buzz or veneer chips. Insist on original grilles, spikes, and demo to confirm no dry treble edge or low-end bloom at volume; at 20kg each, shipping wear matters too.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
