SOLSTICE TECHNOLOGIES
The TRIANGLE R&D explains its work :
“We wanted to bring something new to this range, both in terms of acoustics and design. SOLSTICE embodies the evolution of the ESPRIT range, whilst reflecting the design language and philosophy of what we do today.”
TZ2540MG
NEW HORN TWEETER
The tweeter incorporates many of the innovations developed for SOLSTICE. Its overall optimisation improves the consistency of high-frequency sound reproduction, delivering a more open, detailed and immersive listening experience.
BARREL STRUCTURE
At the entrance to the horn is a barrel-shaped cut-out that causes volumetric compression at the suspension. This geometric structure optimises the frequency response, resulting in better integration with the midrange driver.
OPTIMISED HORN
The driver profile has been fully optimised in accordance with the OS-SEW (Oblate Spheroid Super Elliptical Waveguide) principle. This geometry promotes a more uniform distribution of high frequencies throughout the listening area, ensuring a wider and more stable soundstage.
HERITAGE AND PERFORMANCE
TRIANGLE MAGNESIUM DOME
The SOLSTICE tweeter builds on the acoustic fundamentals that have made the brand’s reputation, featuring a 25 mm aluminium/magnesium dome. This alloy, which has already been tried and tested in the ESPRIT 40TH and MAGELLAN 40TH ranges, is renowned for its lightness and rigidity, enabling it to produce precise and detailed high frequencies.
BACKWAVE ABSORPTION
HIGH-PERFORMANCE ENGINE
The tweeter in the SOLSTICE speakers features a high-power magnetic engine based on a neodymium ring with an open centre. Combined with a rear absorption chamber, this design helps to limit internal reflections and reduce distortion.
CONSISTENT SOUND DISTRIBUTION
NEW PHASE PLUG
With a view to optimising high-frequency dispersion, the phase-alignment component has been specifically redesigned.
Now moulded as a single piece, it features a design inspired by the ‘barrel’ principle, ensuring better control over the propagation of sound waves.
Its redesigned structure allows for a more uniform distribution of high frequencies throughout the room and widens the listening area, ensuring a more consistent sound reproduction and constant sound quality, even off-axis from the speakers.
NEW BASKET
NEW DRIVER ARCHITECTURE
Developed specifically for SOLSTICE, the new 16cm die-cast aluminium basket features an arch-shaped structure offering exceptional acoustic neutrality.
Its design combines mechanical rigidity with optimised airflow, preserving acoustic performance even at high listening levels.
EMISSIVE SURFACE EXTENSION
NATURAL CELLULOSE PULP MIDRANGE
The cone benefits from a new rear-glueing system that increases the radiating surface area and improves the linearity of the reproduction, both acoustically and visually.
Made from natural cellulose pulp, a signature material for TRIANGLE, it stands out for its ability to reproduce voices and instruments with warmth and realism.
A SOLID FOUNDATION
The R&D department has carried out extensive engineering and acoustic optimisation work to improve the low-frequency performance of our speakers.
WOOFER
On the Solstice 8, the low frequencies are handled by new 16 cm drivers featuring a concave membrane with no dust cap. This design results in a particularly rigid cone, minimising distortion under heavy load and promoting more accurate reproduction of low frequencies. Their design also contributes to the speaker’s sleek aesthetic, providing a continuous, uniform surface that reinforces the visual identity of the SOLSTICE range.
MIDWOOFER
The mid-woofer driver has been developed to offer an optimal balance between energy, natural sound and versatility. Its natural cellulose pulp cone stands out for its ability to reproduce timbres with finesse whilst maintaining excellent responsiveness. Capable of covering a wide frequency range with great consistency, it ensures a smooth transition between the bass and midrange registers. Vocals gain presence, instruments gain body, whilst the lower end of the spectrum retains all its dynamics and impact.
A BALANCE BETWEEN REGISTERS
HIGH-QUALITY INTERNAL COMPONENTS
Invisible to the listener but essential to the sound balance, the crossover plays a central role in the performance of the SOLSTICE speakers.
Optimisation of the slopes, phase response and choice of components ensures a smooth transition between frequency bands, guaranteeing a natural and perfectly balanced sound reproduction.
Each crossover is constructed using carefully selected components, combining air-core inductors, MKT capacitors and cement-coated resistors, in order to preserve the signal’s integrity.
| Crossover frequencies | Bass crossover type | Midrange/Midwoofer crossover type | Treble crossover type | |
| Solstice 3 | 2,8 KHz | - | 2nd-order low-pass | 3rd-order high-pass/td> |
| Solstice C3 | 2,85 KHz | - | 2nd-order low-pass | 3rd-order high-pass |
| Solstice 8 | 250 hz / 3,7 KHz | 2nd-order low-pass | 2nd-order band-pass | 3rd-order high-pass |
SOUND CONTROL
ROUNDED EDGES
For SOLSTICE, the pursuit of performance is also achieved through a cabinet with high inertia. Its design helps to create a stable structure, allowing the drivers to perform to their full potential.
The rounded edges minimise diffraction caused by side effects and promote a more uniform dispersion of sound throughout the room. This approach results in a more precise sound image and a more natural soundstage.
DVAS TECHNOLOGY
MECHANICAL EXPERTISE AND ACOUSTIC PERFORMANCE
A REINFORCED STRUCTURE
The structure also benefits from the DVAS (Driver Vibration Absorption System), where a high-density perforated reinforcement abuts the driver via a damping material, thereby stiffening the driver/cabinet assembly.
A high-density EVA foam gasket, positioned at the end of each internal reinforcement, ensures contact between the speaker driver and the reinforcement. This greatly dampens the transducer vibrations generated by the movement of the diaphragm, with only a small residual vibration being transmitted to the cabinet.
SOLSTICE TERMINALS
OPTIMAL CONNECTION
The terminal block for the SOLSTICE range has been completely redesigned to combine performance with aesthetic integration.
Crafted from highly conductive materials, these new connectors ensure optimal signal transmission and offer broad compatibility with various connection types. Their exclusive design, finished in champagne, blends seamlessly with the range’s refined aesthetic.
The Solstice 3 and Solstice C3 models feature a single terminal block, whilst the Solstice 8 benefits from a dual terminal block allowing for bi-wiring or bi-amping.
