Triangle Electroacoustique Signature deltas Floorstanding Loudspeakers This is a very reluctant sale of some fantastic floor standing speakers, they're immediate, clear and have some real impact. These have been serviced at Impulse Audiovisual where two of the mid range drivers were replaced with genuine triangle parts. The speakers themselves are furniture grade and been maintained in excellent order. There is only one real visible flaw which is the edging of one of the speaker covers (see picture) - otherwise they're perfect. Reviews as follows: https://www.stereophile.com/content/triang
This is a strong buy in what remains a seller’s market for high-end French floorstanders, as A$4,000 sits well below the typical used range for Triangle Signature Deltas. New prices have hit A$16,000–A$17,000 per pair (roughly $8,500–$9,000 USD), and even used listings rarely dip under A$10,000, putting A$4,000 near or below the 25th percentile—a genuine bargain for a clean pair.
The Signature Delta is a revered three-way, ported design known for its paper-cone midrange, TZ2500 tweeter, and 92dB sensitivity that delivers airy, dynamic sound with deep bass down to 35Hz. At this price, you’re getting a rare chance to own a flagship Triangle speaker with exceptional tonal realism and build quality, especially if it’s original-owner, excellent-condition, and includes stands or cables. With no red flags in the listing, this is a clear buying opportunity for anyone seeking high-performance French hi-fi without the new-price shock.
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.
