Sonos Beam Ultra Review: Real Height Drivers, At Last

The Sonos Beam Ultra is Sonos's new mid-size soundbar, slotting between the entry-level Ray and the flagship Arc Ultra. Sonos opened pre-orders on 1 September 2026 at its own store and select US retail partners, with general availability from 29 September. It comes in black or white with a matte finish. Importantly, it does not replace the Beam Gen 2, which stays on sale as the more affordable Dolby Atmos option — so Sonos now has four soundbars rather than three. The Beam Ultra is for rooms where an Arc Ultra is physically too long or too much bar for the television, but virtualized height has stopped feeling like enough.

What Sonos has confirmed about the Beam Ultra:

• Nine custom drivers with nine amplifiers: five tweeters and four low-profile woofers
• Two tweeters fire upward through directional horns for Dolby Atmos height; two fire sideways for stereo width; one faces forward for the center
• Sonos describes the result as a true 7.1.2 Dolby Atmos presentation
• Redesigned center channel plus AI Speech Enhancement with four selectable levels, and Night Sound
• Trueplay room correction, now available from both iOS and Android devices
• HDMI eARC and ARC, Wi-Fi 6, Bluetooth 5.3 and Apple AirPlay 2
• USB-C accepts an analog source through the optional line-in adapter, or wired Ethernet through the combo adapter
• Dolby Atmos via Dolby Digital Plus and Dolby TrueHD, plus Dolby Digital, multichannel PCM and DTS Digital Surround
• 29.53 inches wide, 2.48 inches high, 4.13 inches deep; wall-mountable

The Beam Gen 2 used five Class D amplifiers, a single center tweeter, four elliptical mid-woofers and three passive radiators, and produced its Atmos height entirely through processing. The Sonos Beam Ultra adds physical height transducers, which is a structural change rather than a firmware one. Driver count rises from five to nine, and side-firing tweeters now widen the stereo image. The bar grew: it is longer and slightly slimmer than the Beam Gen 2, at almost identical weight. Connectivity gains Wi-Fi 6 and Bluetooth. Dialogue control is new, with four levels of AI Speech Enhancement instead of a single on-off toggle, and Trueplay now runs on Android as well as iOS.

Journalists who heard the Sonos Beam Ultra at launch demonstrations in Berlin and New York consistently flagged the same thing: the width. Reports describe positional Atmos effects landing well off to the sides, with a sense of scale that outruns the bar's physical size and, in several accounts, some larger soundbars too. Directional accuracy, bass warmth and vocal clarity were all singled out as improvements over the Beam Gen 2. The system features matter as much as the sound, though. Sonos 27 lets a matched pair of portable Sonos speakers act as wireless rear channels and then go back to being portable speakers, and TV Audio Swap pushes the soundtrack to compatible Sonos headphones.

Two omissions are hard to defend at this tier. There is no DTS:X support, despite DTS Digital Surround being on the format list, which matters if your library leans on physical discs. And there is still a single HDMI connection with no passthrough, so every source has to go through the television first. The price jump over the Beam Gen 2 is substantial, which pushes the Beam Ultra into a bracket where Bose and Samsung both sell nine-driver Atmos bars, and Samsung includes a wireless subwoofer in the box. Full reviews were still landing at launch, so long-term sound judgements were not yet available when pre-orders opened.

Buy the Sonos Beam Ultra if you already own Sonos speakers and want a compact bar that grows into a real system — portable surrounds, a Sub, headphone handoff and all. Buy it if your TV cabinet cannot take an Arc Ultra. Skip it if you want the most hardware for the money, because rivals bundle subwoofers at similar prices. Skip it if you play physical media encoded in DTS:X, which the Beam Ultra simply will not decode. And skip it if the Beam Gen 2 already does what you need, since Sonos is keeping it on sale precisely for that reason.

The Sonos Arc Ultra remains the flagship, with 14 drivers, a Sound Motion woofer and a 9.1.4 layout, and is the right answer for larger televisions and bigger rooms. Bose's Smart Ultra Soundbar takes a similar nine-speaker approach with two up-firing drivers, ADAPTiQ calibration and AI Dialogue Mode, and Bose includes the calibration headset in the box. Samsung's HW-QS700F ships a wireless subwoofer alongside a 3.1.2 bar and integrates with Samsung televisions through Q-Symphony. And the older Sonos Beam Gen 2 is still there if virtualized height is good enough.
