DUO GT

The DUO GT “Grande Twin” is the third evolutionary stage of a horn system that has been in Avantgarde Acoustic’s portfolio since 1993. The proven innovative spherical horn architecture combined with the improved XM2 midrange driver, the new XT3 Supertweeter from the TRIO and the XB12 bass drivers with huge voice coil from the SPACEHORN.

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. Because in the captivating world of spherical wave horns, size is the defining criterion. The larger the dimensions of the horn, the deeper its lower bandwidth and the more the listener enters the maelstrom of superior performance.

The EvolutionAA XM2 midrange driver – a 170 mm chassis with a powerful Alnico magnet – is designed for a large linear diaphragm excursion. Its new “soft mesh compound” diaphragm uses a sturdy mesh carcass as the basis of its construction. The microscopic openings of the mesh are sealed with a damping elastomer coating. The combination of the solid mesh structure with flexible lining develops a broadband absorption effect that effectively dampens partial vibrations of the diaphragm and thus unwanted harmonics.

The DUO GT uses the XT3 tweeter from the TRIO G3. The XT3’s lighter, annular diaphragm extends the frequency range up to 28,000 Hz at a sensitivity of 107 dB, providing greater clarity, focus, and a fuller, more natural sound.

By using two powerful XB12 drivers in a bass-reflex configuration, the dynamic headroom of the bass has been virtually doubled compared to its predecessor. We have increased the voice coil from 100 mm of the previous model to 153 mm. This gigantic motor structure with a diameter of 6 inches achieves superior values of the power factor and power handling. At the same time, thermal compression is significantly reduced.

The G3-1000 bass amplifier has 1,000 watts and is equipped with an advanced digital sound processor. The new user interface allows easy adjustment of the sound to individual preferences and seamless integration of the system in a wide variety of rooms.
