Opposites captivate us: a compact horn speaker delivering powerful sound performance. The UNO combines minimalist design with lavish, sophisticated technology. It’s the perfect entry into the world of classic horn loudspeakers, standing out with minimal competition.

Excellence reinvented.

G3 represents “Generation 3,” the evolution beyond the renowned XD series. Building on the legacy of the original Generation 1 models from 1993, this marks only the second complete technology and product platform renewal in 30 years.

The G3 Series pushes the natural horn principle to its extreme, delivering unmatched musical power through exceptional efficiency and an extended frequency range.

Optional with the iTRONAA fully active modules, featuring patented GameChanger technology, which directly controls membrane acceleration through precise current flow. This results in perfect, distortion-free, crystal-clear, and natural sound that closely mimics a live performance.

Experience incredible detail, stunning dynamic range, exceptional spaciousness, and customizable bass performance with the G3 Series.

Gy8 Audio Review
“The Uno SD is a speaker that has come from left-field to stand firmly in the centre-circle, with traditional hi-fi qualities that are directly comparable to its price peers and performance benefits that take it onto another level entirely.”

Enjoy the Music
“The midrange of the UNO SDs was the main component of the vast soundstage that these speakers produced. The instruments on the album appeared as distinct entities within this cloud of sound that filled the space between the speakers and went way back behind them. The reverb applied to many instruments created a sonic nebula, and I could “see” this image surrounding each sound in the vast soundstage.”
