Triangle Launches Solstice Loudspeakers: Introducing New Horn Tweeters and French Driver Technology

The Triangle Solstice replaces the Esprit with a new horn tweeter, French-made drivers, a modified cabinet, and options for stereo to home cinema.

Triangle has replaced its long-standing Esprit series with a new loudspeaker lineup called Solstice, developed and manufactured in France's Soissons. More than just a facelift, the Triangle Solstice series introduces redesigned horn tweeters, new driver structures, modified cabinet construction, and an integrated bass designed to provide a more cohesive platform for next-generation stereo speakers.

For over 30 years, Triangle's Esprit series has built a reputation for high sensitivity, natural tonal balance, and exceptional value. The Solstice carries the torch forward, aiming to preserve the musical characteristics associated with Triangle loudspeakers while introducing new technologies across the lineup.

Rather than another evolutionary Esprit update, the Solstice is a completely new development from the ground up. Triangle states that all major components have been redesigned, with particular attention paid to frequency consistency, cabinet rigidity, and the reduction of unwanted coloration.

A Completely New Loudspeaker Series

The Solstice line comprises three models: the Solstice 8 floorstander, the Solstice 3 bookshelf speaker, and the Solstice C3 center channel. Designed as a consistent platform for both stereo and home cinema systems, this series shares Triangle's new driver technology, crossover approach, and cabinet construction. Finishes include white, black, teak, and birch, with matching stands available for the Solstice 3.

Triangle Solstice 8 (Birch)

The Solstice 8, the flagship floorstander, utilizes a 3-way bass reflex design featuring a 25mm horn-loaded tweeter, a 16cm cellulose pulp midrange driver, and a pair of 16cm concave cone woofers. Triangle specifies a frequency response of 38Hz to 22kHz and an RMS allowable input power of 130 watts. The dual terminal arrangement supports conventional single wire connection, bi-wiring, or bi-amping. The Solstice 8 is intended for rooms approximately 15 to 50 square meters, or roughly 160 to 540 square feet.

Triangle Solstice 3 (White)

Solstice 3: The compact standmount features a 25mm dome tweeter and a 16cm cellulose pulp midrange/bass driver in a 2-way bass reflex design. Triangle specifies a frequency response of 48Hz to 22kHz and an RMS allowable input of 90 watts. The cabinet base is designed to integrate directly with the matching S05 stand for the Triangle. Solstice 3 is recommended for rooms approximately 10 to 35m², or about 108 to 377 square feet.

Triangle Solstice C3 (Black)

Solstice C3: The center channel features a 25mm dome tweeter and twin 16cm cellulose pulp midrange/bass drivers in a 2-way sealed design. It can be placed horizontally below the display or used vertically as a left or right channel. Triangle specifies a frequency response of 50Hz to 22kHz, an RMS allowable input of 120 watts, and a sensitivity of 92dB. This sensitivity closely matches that of the Solstice 8 and Solstice 3, helping to maintain consistent tonal balance across the entire front soundstage in a matched home cinema system.

Speaker Drivers

Instead of modifying existing units from the Esprit series, Triangle developed all Solstice drivers specifically for the new lineup. The goal was greater consistency between models and sharing driver technology and voicing across stereo and home cinema configurations.

Tweeter Innovation

All three Solstice models utilize Triangle's new TZ2540MG horn tweeter. According to Triangle, this design combines two acoustic concepts that have never been used together in any of the company's tweeters before.

Triangle Solstice 3 (Teak)

The horn profile follows the OS-SEW (Oval Super Elliptical Waveguide) principle, which Triangle says promotes more even high-frequency dispersion. Claimed benefits include a wider listening area, a more stable soundstage, and a more consistent tonal balance beyond the central listening position.

The barrel-shaped cutout at the base of the horn is designed to create volume compression near the suspension point. According to Triangle, this improves behavior around the crossover region and supports smoother integration between the tweeter and midrange driver.

The TZ2540MG uses a 25mm aluminum/magnesium alloy dome, which Triangle says is based on materials used in the Esprit 40th Anniversary and Magellan 40th Anniversary series. The company states that this alloy increases the stiffness of the diaphragm while helping to reduce metallic coloration often associated with pure aluminum domes.

The tweeter also integrates a neodymium ring motor with an open center and rear absorption chamber. Triangle says this configuration is intended to limit internal reflections and reduce distortion.

At the tweeter's output, Triangle has adopted a newly designed integrated phase plug. This geometric structure, injection molded as a single component, takes inspiration from the barrel shape of the horn. The design is intended to promote more even high-frequency dispersion and more consistent off-axis performance.

Midrange and Bass Drivers

The 16cm drivers utilize a new arched diecast aluminum basket designed to increase structural rigidity while improving airflow around the rear cone. Triangle says the modified structure also helps limit basket resonance, which can affect midrange clarity, especially at higher listening levels.

Triangle continues to use natural cellulose pulp for the midrange cones, a material the company associates with neutral tonal balance and natural reproduction of voices and instruments. A new rear adhesive assembly process is designed to increase the effective radiating surface area and improve linearity across the driver's operating range.

The Solstice 8 uses a concave cone and a twin-bass driver without a traditional dust cap. Triangle says the concave profile creates a firmer radiating surface, which helps reduce distortion at higher amplitudes while maintaining clean and controlled low-frequency output. It also gives the driver a cleaner and more unique look.

Cabinet Construction

Triangle says its Solstice enclosures are engineered for acoustic neutrality, aiming to minimize the cabinet's contribution to the reproduced sound.

The company's DVAS (Driver Vibration Absorption System) integrates the driver into the speaker structure to help reduce vibrations. Triangle says this approach increases cabinet rigidity and attenuates vibrations generated by the midrange driver, providing intended benefits of greater clarity, detail, and dynamic expressiveness.

The Solstice cabinets are constructed from high-density MDF. The Solstice 3 weighs 12.9kg (28.4 pounds), the Solstice C3 weighs 11.75kg (25.9 pounds), and each Solstice 8 weighs over 30kg (66 pounds). All external cabinet edges are rounded to reduce diffraction and support more even sound dispersion, and Triangle says this contributes to more precise stereo imaging.

Crossover and Connectivity

The crossover network uses air core inductors, MKT capacitors, and cement coated resistors, with OFC (Oxygen Free Copper) internal wiring throughout.

The Solstice 8 features dual binding posts for bi-wiring or bi-amping, while the Solstice 3 and Solstice C3 use a single terminal block. All models accept standard speaker cable terminals including banana plugs and spade connectors.

Integrated Base

The Solstice 8 introduces Triangle's new integrated base, which combines mechanical isolation, vibration control, and bass reflex loading into a single structure.

Its hidden laminar bass reflex port routes the bass through the cabinet itself rather than an exposed port opening. Triangle says the laminar design is intended to reduce turbulence and port noise by eliminating visible port openings from the enclosure.

The base uses a dual-material construction combining a cast iron honeycomb structure with a thick silicone outer layer. The cast iron is intended to add mass and rigidity, while the silicone layer helps absorb vibrations and mechanically isolate the loudspeaker from the floor.

Triangle also incorporated a 2-degree rearward tilt into the base to better align the tweeter output with seated listening positions and widen the usable listening area.

The Solstice 8 includes adjustable spikes and counter spikes for solid floors or carpeted rooms. The Triangle logo cap conceals the hardware after installation.

Exterior Finish

Solstice speakers are available in four finishes: teak, birch, white, and black ash. The wood effect options use a vertical grain direction, and each model includes a color-matched magnetic grille.

Sculpted silicone surrounds encase each driver, matching the cabinet finish, while a champagne finish aluminum trim ring adds further refined visual detail around the drivers.

S05 Stand with Triangle Solstice 3 (Birch)

The optional S05 stand is specifically designed for the Solstice 3 and is available in black, white, teak, and gray finishes, the latter intended to complement the birch finish. The speaker's base locks directly into the top plate of the stand for a more secure and visually integrated installation.

Triangle Solstice Series Specifications

Triangle doesn't treat the Solstice as a simple everyday Esprit refresh with new veneers and some upgraded crossover components. The new line incorporates a TZ2540MG hybrid tweeter, a new 16cm cellulose pulp driver, DVAS cabinet construction, modified crossover, and for the Solstice 8, a meticulously engineered integrated bass system combining mechanical isolation, a hidden laminar bass reflex port, and a 2-degree listening axis tilt.

As a result, the Solstice is more appealing to music listeners who want a properly engineered and visually distinctive French loudspeaker system rather than just another generic rectangular box with familiar driver complements. The Solstice 8 will appeal to buyers looking to build a serious two-channel system in medium to large rooms, while the Solstice 3 and C3 offer a logical path towards a matched stereo or three-channel front soundstage.

The limitation is, at least for now, the system's width. Triangle launched the Solstice as towers, standmounts, and center channels but lacks dedicated surround, on-wall, height speakers, or matching subwoofers. This makes it highly suitable for stereo and front stage home cinema systems but falls short of perfection for buyers planning a fully matched Dolby Atmos setup.

Competition will come from Focal's Tebia series, DALI's SONIK range, Perlisten's A-series, and Elipson's Prestige Facet II lineup. Focal offers French design and slate fiber driver technology. DALI SONIK provides a broader home cinema ecosystem. Perlisten delivers more explicitly performance-oriented engineering and dedicated on-wall surround options. Elipson offers the widest model selection, including surround, Atmos, LCR, center, bookshelf, and tower options.

Triangle's advantage is that the Solstice feels less like a simple replacement range and more like a comprehensive acoustic redesign, with the hybrid tweeter, cabinet engineering, and the Solstice 8 bass carrying most of the weight.
