AVANTGARDE DUO SD

The new entry into the world of DUO sound.

Driven by its impressive 670 mm spherical wave horn with a frequency response up to 170 Hz, the DUO is the epitome of performance and dynamic elegance. In the fascinating world of spherical wave horns, size is the defining criterion. The larger the horn, the deeper its lower bandwidth and the more the listener is drawn into the maelstrom of superior performance.

The Evolution XM2 midrange driver – a 170 mm

One speaker. Two versions.

SEMI-ACTIVE VERSION.

The semi-active version is designed to be used with external hi-fi amplifiers.
With an efficiency of 107dB/W/m and an impedance of 18 ohms, the speaker is extremely easy to operate and ideal for low-power amplifiers. The ideal speaker for the world’s finest high-end amplifiers.

iTRON VERSION.

In the iTRON version, the amplifiers are built into the speaker, eliminating the need for external power amplifiers. To achieve this, we have developed an electronic system that is based on a fundamentally different operating principle to any of the conventional amplifiers on the market. We are the first manufacturer in the world to achieve what was previously thought to be an impossible technological feat. For a sound that is simply heavenly.

Modular technology for versatility & timelessness.

Each model has a replaceable technology module that connects to the loudspeaker via a multi-pin power connector. This makes it easy to upgrade the semi-active speaker with iTRON technology at a later date.

It can be upgraded to the most advanced digital technology available at the time, even after many years.

This ensures the sustainability of your investment for generations to come.

Coplanar alignment of the drivers.

In the speaker, all the drivers are on the same axis. This means that the acoustic centres are all in the same plane. The distance between the acoustic centres of the drivers and the listener is therefore always identical.

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 complex capacitor, handmade in Germany. The electrodes are made from precision-rolled aluminium foil, rather than ultra-thin plastic film vaporized with aluminium. The dielectric is a cellulose fibre compound impregnated with organic oils. The NatureCap is approximately 25 times larger than the previous XD series capacitors and is securely mounted to the circuit board using specially manufactured brackets.
