AVANTGARDE UNO SD

Our compact G3 system.

The UNO SD is a scaled-down version of the classical DUO system. The objective was to accomplish the clarity and power of its “bigger“ brother in a significantly reduced enclosure.

The 500mm spherical midrange horn covers a wide bandwidth down to 300 Hz. Midrange and tweeter drivers are equipped with Omega voice coils. With this high-impedance technology, we improve the interaction of membrane movement and amplifier signal. The result is an 18 ohms impedance combined with 107 dB system sensitivity.

The EvolutionAA XM1 is a 127 mm midrange horn driver optimized for large, linear excursion. Its new “SoftMesh–Compound” membrane uses a stable grid carcass as its structural foundation. The microscopic apertures of the grid are sealed with a proprietary synthetic elastomer coating. Combining a stable grid structure with a flexible lining effectively reduces partial resonances of the dome itself and absorbs distortions.

For the UNO SD, we completely redesigned the tweeter assembly. The XT2 tweeter's lighter, annular diaphragm extends its frequency range up to 22,000 Hz with 107 dB sensitivity, ensuring greater clarity, focus, and harmonic resolution, a fuller and more natural sound. The UNO SD is combined with a powerful subwoofer module, utilizing our new powerful XB10 driver in a bass reflex configuration.

We have increased the voice coil from 100mm (of the old UNO) to 153mm. This gigantic 6-inch diameter motor structure achieves astonishing levels of force factor and power handling, while at the same time significantly reducing thermal compression.

The G3–500 bass amplifier of the UNO SD has 500 watts and is equipped with an advanced digital sound processor. The new user interface allows for a simple adjustment of the sound to individual preferences and seamless system integration in different rooms.

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.
