SONOS FABER DUETTO - ACTIVE WIRELESS LOUDSPEAKERS
/Sonus Faber are an Italian company based in Vicenza, in the Veneto region, known for creating high-quality loudspeakers that balance impressive sound with elegant, thoughtful design. Their approach combines traditional craftsmanship with modern engineering, resulting in speakers that look as good as they sound.
Design
The Duetto speakers share much of the design detail found in the Sonetto range and, unsurprisingly, look stunning — Italian craftsmanship at its finest.
They bring together traditional skills with cutting-edge technology. The cabinet cross-section is lute-shaped to minimise standing waves, which reduces colouration and distortion. I particularly love how the rear port has been seamlessly integrated with the heat sink; so much care and attention lavished on a part of the speaker you might never even see in daily use.

The tops are wrapped in leather, giving a wonderfully premium feel under the fingertips. The master speaker features LED strips cleverly cut into the leather — more on these shortly.
Two finishes are available: walnut and graphite. The walnut veneer is laid at a 45-degree angle, lending the speakers a distinctive and elegant appearance that stands out in any room.
The undersides are finished with a rubber pad for effective isolation, helping the speakers perform at their best no matter the surface.

Technology
A 250-watt Class D amplifier drives the 133mm mid/bass unit, while a 100-watt Class A/B amplifier powers the 28mm silk dome tweeter. Both drivers are designed and manufactured in-house by Sonus Faber — no off-the-shelf units here.
The stated frequency range is an impressive 37Hz to 30,000Hz, though, as always, the measurement criteria are not specified.
The Duetto use the very latest Ultra Wide Band (UWB) technology, allowing robust communication between the two speakers. This wireless transmission is designed to eliminate latency and avoid interference from other networks, while delivering high-speed data across a wide frequency band.
Connectivity
The master speaker (which can be positioned either left or right) has its inputs discreetly located on the bottom rear panel. You’ll find connections for mains power, Ethernet, MM/line input, HDMI eARC, and optical digital input. There’s also a subwoofer output, which opens up a range of flexible configuration options in the app.
Wireless connectivity covers all the bases:
AirPlay 2
Chromecast
Spotify® Connect
Tidal Connect
QQMusic
Bluetooth AptX HD and SRC
They’re also Roon Ready, making them a superb choice for streaming high-resolution music with ease.

Control
Source selection and basic functions can be operated directly from the touch-sensitive LEDs and buttons on the master speaker’s top panel. A small remote control is included, but most people will find themselves using the excellent Sonus Faber app.
The app enables detailed setup, including boundary compensation, high-frequency adjustments, balance, and a loudness selector — which, by default, is switched on. Personally, I find the speakers sound even better with this defeated.

A neat touch: the master speaker’s LED strip changes colour depending on the source selected, providing clear, intuitive feedback.
Auditioning
When you first power up the Duetto, the master speaker’s LEDs perform a playful little animation — a small touch, but one that hints at the care and attention to detail Sonus Faber pour into every aspect of their design. I’d be fibbing if I said I haven’t powered them down a few times just to watch it again!
I started my listening with Charlie Rich’s If You Wouldn’t Be My Lady. The vocals emerged deep, crisp and beautifully clear, with a warmth and texture that draws you straight in. The midrange presence is simply superb — voices sound human and lifelike, not processed or clinical.
Next up, Californian Soil by London Grammar demonstrated just how effortlessly the Duettos fill a room. They’re more than capable of going loud — very loud if you want them to — and the low end is remarkable for speakers of this size. Bass notes hit with satisfying weight and control, but never overwhelm the rest of the music.
I then put on Messy by Lola Young, one of my favourite new discoveries. The Duetto presented this track with real authority and poise. There’s an impressive sense of scale; the soundstage extends well beyond the speakers themselves, with instruments and vocals precisely placed. The build-up in the song is handled beautifully, showcasing the dynamic range and the effortless way these speakers transition from delicate passages to big, bold crescendos.
I also tried a few lower-quality streams to see how forgiving they’d be — and while they certainly reward good recordings, they don’t punish poor ones, making them enjoyable for everyday listening, no matter the source. In short, they’re serious performers that never forget music should be fun.
Conclusion
In my view, the Sonus Faber Duetto are a brilliant choice for anyone who wants uncompromising sound quality, stylish design, and the convenience of a modern wireless system — all without needing a rack full of separates and a nest of cables. They prove that you don’t have to sacrifice performance for practicality.
They’ll look equally at home in a contemporary living room or a more traditional space, and their understated elegance means they complement your décor rather than dominate it. Whether you listen quietly with a glass of wine in the evening or want to fill the house with music at the weekend, they’ll do it all with confidence and charm.
If you’d like to experience what the Duetto can do, Andy and I would be delighted to set up a demonstration for you in our showroom. Feel free to bring along your favourite music — these speakers deserve to be heard with tracks you love.
Thanks for reading — we look forward to welcoming you soon.
