Seller's Description

Subwoofer som passar både musik och film

Our Thoughts RADAR AI

At SEK 6,000, this Triangle Thetis 380 is a strong bargain, sitting well below its typical used market range of roughly SEK 7,500 to SEK 9,000, especially since its original new price was approximately SEK 13,000 (€1,200). This subwoofer is Triangle’s most powerful model, delivering 350W RMS with a 30cm cellulose-carbone composite driver for deep, precise bass from 20Hz to 120Hz, making it ideal for both hi-fi and home cinema. Its class-D amplifier, bass-reflex design, and full connectivity (LFE, RCA, high-level) offer significant performance upside, while the clean listing and original-owner condition present a rare buying opportunity for enthusiasts seeking high-end low-end without the new price tag.

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.
