Triangle - Solstice 3 - Bookshelf Speaker

The successor to Triangle's iconic Comète. A new TZ2540MG barrel-shaped magnesium alloy horn tweeter. A 16cm natural cellulose midwoofer with DVAS vibration absorption. A laminar bass-reflex base. The Triangle Solstice 3 delivers a wide sound spectrum, realistic vocals, and a lively, expressive performance — well beyond what a bookshelf speaker typically promises.

An Icon Reimagined

There are bookshelf speakers that fill a shelf. And there are bookshelf speakers that fill a room. The Triangle Solstice 3 emphatically belongs in the second category — the successor to Triangle's beloved Comète, one of the most acclaimed compact speakers in French hi-fi history, reimagined for a new era with new drivers, new technologies, and a new level of refinement.

More balanced. More precise. More musically engaging than any bookshelf speaker at its size and price should reasonably be. The Solstice 3 combines natural timbres, rich detail, and a wide soundstage that punches far beyond its compact dimensions — with vocals that gain in presence, instruments that gain in clarity, and low frequencies that are perfectly controlled rather than merely present.

It is, in every sense, a new benchmark for what a Triangle bookshelf speaker can achieve.

TZ2540MG — The New Horn Tweeter

The headline acoustic innovation of the Solstice range is the TZ2540MG — a 25mm barrel-shaped magnesium alloy horn tweeter built around two new acoustic architectures developed specifically for this family of speakers.

A new phase plug optimises the dispersion of high frequencies across the listening field, ensuring that the tweeter's output remains extended and consistent well off-axis. A horn with an improved profile and barrel-shaped mouth manages the transition from driver to room with greater precision and lower coloration than conventional dome designs. The result is high-frequency reproduction that is extended, refined, and entirely free from the brightness or hardness that lesser tweeters can introduce — detail and air where the music demands it, restraint and naturalness everywhere else.

16cm Natural Cellulose Midwoofer — DVAS Vibration Absorption

The 16cm midwoofer at the heart of the Solstice 3 is built around a new die-cast aluminium basket with Triangle's arch-shaped acoustically neutral structure, and features a natural cellulose pulp membrane — chosen for its ability to reproduce timbres with finesse whilst maintaining excellent responsiveness across a wide dynamic range.

Uniquely, the Solstice 3 incorporates Triangle's exclusive DVAS (Driver Vibration Absorption System) — a design that reduces vibrations through the clever integration of the drivers into the speaker's structure, improving the overall rigidity of the cabinet and dampening the unwanted frequencies that driver movement inevitably generates. The sonic result is immediately apparent: sound reproduction gains in clarity, detail, and dynamic contrast, with a more precisely rendered stereo image and a lower overall noise floor.

Laminar Bass-Reflex Base — Innovation at Every Level

The Solstice 3's multi-function base brings together four engineering achievements in a single, beautifully resolved structure — a first for Triangle.

A hidden laminar bass-reflex port reduces flow noise while ensuring dynamic and perfectly controlled low-frequency output. A dual-material base construction — cast iron honeycomb covered with a thick silicone layer — absorbs vibrations and mechanically decouples the speaker from its surface. A 2-degree forward tilt optimises the speaker's directionality and widens the listening field. The result is a bookshelf speaker that is as considered in its mechanical engineering as it is in its acoustic design.

Designed to 360° — Every Detail Considered

The Solstice 3's attention to detail extends to the terminal block — a new design with a champagne finish, compatible with both stripped cables and banana plugs, housed within a silicone ring whose sculpted pattern echoes the cabinet design. The result is a speaker whose visual identity wraps fully around the cabinet, from front to back, with complete coherence.

Paired with the optional Triangle S05 stand — available in Black, White, Teak, and Greige, with aluminium decoupling spikes and rubber caps for all floor surfaces — the Solstice 3 becomes a complete, fully considered listening object. The S05's top plate is precisely dimensioned to the Solstice 3's base for a seamless visual fit.

Hi-Fi and Home Cinema — Equally at Home

The Solstice 3's 90dB sensitivity, 8Ω nominal impedance, and compatibility with amplifiers from 25 to 130 watts per channel make it accessible to a remarkably wide range of systems — from compact integrated amplifiers to high-powered separates. In a home cinema context, it serves equally as a high-performance front speaker in smaller rooms or as a surround speaker in more ambitious, larger setups.

🎵 TZ2540MG Barrel-Shaped Horn Tweeter

A 25mm magnesium alloy horn tweeter with phase plug dispersion optimisation and barrel-shaped mouth — delivering high frequencies that are extended, detailed, and entirely free from brightness or fatigue. The signature acoustic innovation of the Solstice range.

🔊 16cm Cellulose Midwoofer with DVAS

A natural cellulose pulp midwoofer with Triangle's exclusive DVAS (Driver Vibration Absorption System) — reducing cabinet vibrations, improving overall rigidity, and producing sound reproduction with greater clarity, detail, and dynamic contrast.

🏗️ Laminar Bass-Reflex Base — Four Functions

Hidden laminar vent (reduced flow noise), dual-material vibration absorption (cast iron + silicone), 2-degree forward tilt (widened listening field), and seamless visual integration — a first-of-its-kind engineering achievement for Triangle.

🏆 Successor to the Iconic Comète

Building on the legacy of one of Triangle's most celebrated speakers — more balanced, more refined, and more musically expressive than its predecessor, while maintaining the lively, natural character that made the Comète a benchmark compact speaker.
