Sonos could be preparing one of its most important home-cinema launches in years, with a new compact soundbar appearing in US regulatory filings just weeks before the company’s confirmed September product event.
The unannounced device is identified in recent reporting as model S59 and carries the internal codename Gambit. Its proportions reportedly resemble the existing Beam (Gen 2), making a third-generation Beam — or a similarly positioned replacement — the most obvious possibility.
Nothing is official yet. Sonos has not confirmed the product’s retail name, price, specifications or release date, so the details below should be treated as what the evidence currently suggests rather than a confirmed product announcement.
What the FCC filing tells us
The new hardware received FCC authorisation in August. Reports examining the filing say it supports Bluetooth alongside Wi-Fi across the 2.4GHz, 5GHz and 6GHz bands, potentially giving the new model a substantial connectivity upgrade over the current Beam.
Ecoustics reports that the S59 carries product code RM059 and that the filing references the Gambit codename. Key documents including detailed photographs and the user manual remain confidential, which means the speaker configuration and final feature set are still unknown.
That uncertainty matters. A regulatory filing can tell us that hardware exists and reveal some of its wireless capabilities, but it cannot yet tell us whether Sonos has solved the biggest limitations of its current compact soundbar.
A Beam successor makes sense
The Beam (Gen 2) launched in 2021 and remains the middle option in the Sonos soundbar range. In the UK, Sonos currently lists the Beam (Gen 2) at £449, sitting below the flagship Arc Ultra.
Five years is a long time in home cinema. TVs have become more capable, HDMI 2.1 features are increasingly common and Dolby Atmos has moved from a premium extra towards an expected feature on mid-range soundbars.
Sonos has already modernised the top of its range with the Arc Ultra, so refreshing the smaller Beam is a logical next step.
The biggest upgrade we want: real height channels
The Beam (Gen 2) supports Dolby Atmos, but it does not use dedicated upward-firing height speakers. Instead, Sonos uses processing to create virtual height channels.
That approach helps keep the Beam compact, but it also limits how convincingly it can reproduce effects intended to come from above the listener. Sonos itself describes the current Beam as using advanced processing to create phantom height channels.
A new Beam with physical upward-firing drivers would therefore be a meaningful upgrade rather than simply a specification refresh. The challenge will be fitting them into a compact enclosure without pushing the price too close to larger premium soundbars.

HDMI passthrough would make it far more flexible
Another improvement we would like to see is an additional HDMI input for passthrough.
The Beam is designed around a simple single-cable HDMI connection to the television. That works well for many homes, but it means consoles, streaming boxes and other sources rely on the TV having enough HDMI ports and correctly passing audio back through eARC.
A passthrough input would be particularly useful for more complicated home-cinema systems, although Sonos has traditionally prioritised simplicity over adding extra sockets.

Bluetooth and newer Wi-Fi could matter more than they sound
One of the more interesting reported changes is Bluetooth support. The existing Beam focuses on Wi-Fi, AirPlay 2 and the wider Sonos ecosystem, while newer Sonos hardware has increasingly embraced Bluetooth as another way to get audio into the system.
Support for 6GHz Wi-Fi would also bring the compact soundbar closer to Sonos’ newer hardware platform. It may not transform everyday listening by itself, but stronger modern connectivity could improve longevity and give Sonos more headroom for future ecosystem features.
Where does AI fit?
There is another intriguing piece of the puzzle. Sonos CEO Tom Conrad has confirmed that the company plans to introduce new product work in September while discussing how conversational computing and predictive intelligence are moving into the home.
What Hi-Fi reported on Conrad’s comments, although Sonos has not confirmed that the S59 soundbar is the product he was referring to or exactly how AI would be used.
Useful voice control, smarter room optimisation and more adaptive audio processing would make sense for a home speaker. What matters is whether those features improve the listening experience rather than simply adding AI to the specification sheet.
Price could decide whether it works
The Beam occupies an important position because it offers access to Sonos home cinema without requiring buyers to step all the way up to the Arc Ultra. Sonos currently lists the Arc Ultra at £999 before promotional discounts, while the Beam (Gen 2) sits at £449.
A successor needs to preserve that separation. Add enough hardware and the new model becomes much more capable, but allow the price to climb too far and buyers may start looking at larger alternatives from Samsung, Bose and other rivals.

Should you wait before buying a Beam?
If you were already planning to buy a Beam (Gen 2), waiting a few weeks now looks sensible unless you find a particularly strong discount.
Sonos has confirmed a September product launch and the FCC filing provides credible evidence of new soundbar hardware. We still do not know whether it will actually be called Beam (Gen 3), how much it will cost or when it will reach UK shops, but there is enough evidence to justify seeing what Sonos announces before paying full price for the existing model.
Tech Torque Verdict
A new compact Sonos soundbar is overdue, and the S59 filing makes a Beam successor increasingly plausible. Newer wireless connectivity would be welcome, but the upgrades that could genuinely move the experience forward are dedicated height channels and greater HDMI flexibility.
If Sonos can deliver those improvements while keeping the price comfortably below the Arc Ultra, a new Beam could once again become one of the most appealing premium compact soundbars. Until Sonos makes its September announcement, however, the final specification — and even the Beam name — remains unconfirmed.
