Welcome to the most exhilarating, uncompromising, natural and by far the most extraordinary speaker system in the world, the Trio.

The unique Trio.
Unique because its indescribable sound transports the listener without detours to a place where everything mundane is forgotten. World off. Music on.

Das TRIO Konzept.


The Trio is a 3-way ultra high performance horn system. With 109 dB efficiency, it is the absolutely most powerful and therefore distortion-free loudspeaker from Avantgarde.

In the G3 version of the TRIO we have taken the bionic horn principle to the extreme. High-powered horn performance through unrestrained efficiency with a huge frequency range.

Combined with the SpaceHorn – the state-of-the-art development of our legendary BassHorn – for a unique and overwhelming sound experience. Expandable with the iTRON fully active modules of our patented Game Changer technology, with which we directly control the acceleration of the diaphragms through a perfectly orchestrated current flow.

All the electronics are housed in easily replaceable technology modules. So that you can easily expand or upgrade your system even after years.

Excellence reinvented.

With the G3 Series, we have taken the bionic horn principle to the extreme. Highly bred horn performance through unrestrained efficiency with a huge transmission range.

109 dB Efficiency

New Evolution driver generation for extended dynamics and even purer sound.

200 mm - Supertweeter

Innovative XT3 tweeter unit with new Long Throw Horn and extended
Supertweeter frequency range with record-breaking low distortion values.

570 mm midrange spherical wave horn

The Evolution XM3 midrange driver’s Omega voice coil has an impedance of an incredible 27 ohms. Extremely easy to drive for an unparalleled sound with more authority, less distortion and a more precise response.

950 mm bass spherical wave horn

The spherical wave horn of the XL3 fundamental unit has a diameter of 950mm, a length of 650mm and a horn neck opening of 100mm. That’s not only pretty big, but also pretty unique.

Color worlds.

New elegant color and design options for an even more customized configuration of your dream speaker.

Coplanar alignment of the drivers.

In the G3 Series, all drivers are on one axis. This means that the acoustic centers are all on the same plane. The distance of the acoustic centers of the drivers to the listener are therefore always identical. Accordingly, the signals from the respective sources (tweeter, midrange and woofer) arrive at the same time and thus correctly.

Modular technology.

All the electronics are housed in easily replaceable technology modules. So that you can easily expand or upgrade your system even after many years.

Current amplifier.

Patented iTRON current fully active engine for perfect control of membrane vibrations and the ultimate sound.

NatureCap Super Capacitor.

NatureCap the new avant-garde super capacitor with excellent specifications and incredibly delicate sound.

Everything is possible
Each shade in our 12-color collection has been carefully selected by us to adorn your horn speakers. Our claim is that the shades are both timelessly elegant and expressive, integrating harmoniously into your interior design and showcasing the horns.

One speaker. Two version.


The passive version is designed for operation with external HiFi amplifiers.
With 109 dB efficiency and 27 ohms impedance, the speaker is extremely easy to operate and ideally suited even for low-power amplifiers. The ideal speaker for the best high end amplifiers in the world.


In the ITRON version, the amplifiers are built into the speaker and no additional external power amplifiers are needed. For this purpose we have developed integrated electronics based on fundamentally different electro-physical laws than any other amplifier on the market. We have thus succeeded – as the first manufacturer worldwide – in making the technological approach of the current amplifier, which was previously considered technologically unmanageable, work. For a sound that sounds simply heavenly.

Module technology for diversity & timelessness.

Each model has a replaceable technology module that is connected to the speaker via a multi-pin power connector. This makes it easy to upgrade the passive loudspeaker with ITRON technology or the wireless module at a later date.

Even after many years, it is possible to upgrade to the most modern digital technology available at that time.

For a convincing sustainability of your investment – for generations to come.

The style icon among super loudspeakers.

Extraordinary, unique, straightforward.

Even as a shadowy silhouette immediately recognizable as TRIO and absolutely unmistakable.

And that for over 30 years.

Listen & Love

A speaker that communicates a clear brand promise through its appearance.

A speaker that is as visually fascinating as its sound.

The cantilevered tweeter unit.

The frame construction of the tweeter unit is done via an aluminum flat profile with internal concealed cable routing. Through the 35 degree cantilever we break the vertical lines and achieve a progressive silhouette.

The smallest of the three spherical wave horns is thus emphasized in the visual perception.

Light, elegant and always functional.

Due to the design-typical 35-degree angle of the cantilevers, the speaker appears to float above the floor.

The actual adjustable feet or optional spikes are concealed under the foot frame. The special spike mount made of solid aluminum forms an extremely stable composite structure with the foot cross, which prevents vibrations and oscillations.

Coplanar alignment of the drivers.

In the TRIO, all drivers are on one axis. This means that the acoustic centers are all on the same plane. The distance of the acoustic centers of the drivers to the listener are therefore always identical.

The tweeter is mounted on a precision slide rail. The coplanar alignment can thus be precisely fine-tuned.

200mm tweeter horn
  • Lower cut-off frequency with substantially increased acoustic power
  • Smaller and lighter membrane
  • Linear phase response less than 50 degrees (4,000 - 20,000 Hz)
  • 28,000 vibrations per second

The perfect crossover.

With our SphericLowCut filter, Airgate technology and PolarizationPlus circuit, we have developed the most innovative technological concepts in our passive crossover.

These are completed, with the highest quality components available. Our new NatureCap is an extremely intricately designed capacitor, handmade in Germany. Instead of using ultra-thin plastic foils vaporized with aluminum, the electrodes are made of precisely rolled aluminum foil. As dielectric we use a cellulose fiber compound impregnated by biological oils. The NatureCap is approx. 25 x larger than the capacitors from the XD series and is stably attached to the circuit board via specially manufactured brackets.
