“ So close to me and so clear, I didn’t feel lonely that evening.
I knew that when I played that album I’d be able to get away from it all once more, but I didn’t realize I’d be opening up new horizons. They were all there in my living room, the drummer, guitarists, choirs and violins. With my eyes closed, in my own home, a new source of inspiration arose in me, I was swept away.
With my eyes open, I just experienced what I hadn’t dared dream of since being a child - sound exactly as it really is, alive and present! It strengthened my belief that compromise is impossible as far as beauty and performance are concerned. ”
Tweeter Midrange Bass

Tweeter TZ 2500 : natural sound

The tweeter is an essential part of TRIANGLE’s history. It’s a driver designed to reproduce high-frequency sounds such as the cymbals of a drum set or the strings of a harpsichord. The TRIANGLE TZ2500 tweeter owes its exceptional performance to its design: a titanium dome combined with a compression chamber, favoring high efficiency, minimal sound distortion and excellent directivity. The rapid variations in sound or «transitory sounds» are real to life and reproduce an unrivaled «live» sound image.

« All the models in the ESPRIT Ex range, including the «Comète», feature a deeper compression chamber, a titanium dome tweeter and PVC was preferred to aluminum. TRIANGLE has also remodeled the phase plug. When listening, the new tweeter sounds more linear with no fatigue at very high frequencies. The sound is softer and more refined. »

Sam Tellig, Stereophile.

Astonishing reproduction by the midrange

The ESPRIT midrange driver is capable of reproducing all frequencies audible to the human ear. Therefore even the most sensitive ear is capable of perceiving any flaws in the original signal. Based on its experience, TRIANGLE recommends using a cellulose pulp membrane due to its light weight and minimal sound coloration. This membrane, combined with a small pleat peripheral suspension, enables voices to be reproduced with amazing precision.

« Lovers of rich sound, deep colors and soft textures will doubtless appreciate a midrange which is particularly flavorsome and as fruity as a Rhône wine. It is quite uncanny just how the voices and wind instruments produce ripples of sensuality. »

Philippe Venturini, Le Monde de la Musique.

The bass composition

The ALTEA and ANTAL are both equipped with the T16EF100SGC1 driver. With its fiberglass membrane, this driver offers an excellent compromise between stiffness and light weight. A small hole in the membrane ensures effective heat dissipation from the voice coil. In terms of listening, the bass is crystal clear and powerful, and the midrange all the more transparent and natural.


« We worked on the cone in order to dampen any remaining resonance in the «upper bass frequencies» after filtering. In the resulting listening tests, the bass sounds as clear and punchy as it should, and the midrange more natural and transparent. »

spec technology

The Spec (Single point energy conductor) is a brushed steel point.
Like the cello, it evacuates part of the mechanical energy towards the floor, thus improving sound quality. Cabinet vibration is kept to the minimum and has little effect on sound reproduction.

TRIANGLE‘s attention to detail makes all the difference.

a well-thought-out cabinet

vibration control
Cabinet vibration can significantly impede driver performance and it’s therefore an important issue. It can introduce sound distortion and color the musical rendering. A judicious combination of precision volume calculation and bracing enables this phenomenon to be avoided.


choice of finishes
The cabinets offer full quality guarantees. Two finishes are available: the traditional, refined elegance of «cognac» and the contemporary style «black» finish.
