The Sonos Beam Ultra is a compelling $699 mid-size Dolby Atmos soundbar, but the available evidence does not establish that it replaces an individual reviewer’s flagship soundbar. Sonos positions it below the Arc Ultra, and the Beam Ultra’s missing DTS:X support and HDMI passthrough may matter more than its compact footprint to some buyers. Here’s what its specifications and published reviews support—and who should consider it.
What the Sonos Beam Ultra is—and what it isn’t
Sonos announced the Beam Ultra on September 1, 2026, describing it as a mid-size soundbar with nine custom drivers, including two dedicated upward-firing drivers, for 7.1.2 Dolby Atmos. That is Sonos’s stated speaker configuration; the announcement does not make the Beam Ultra the company’s flagship. Reviewers place it between the Beam Gen 2 and the larger Arc Ultra.

On Sonos’s US product page, the Beam Ultra is listed at $699. Its compact dimensions are 29.53 inches wide, 2.56 inches high and 4.13 inches deep; it weighs 6.35 pounds. The box includes the soundbar, power cable, HDMI cable and setup, legal and warranty guide. Sonos lists HDMI eARC, Wi-Fi, Bluetooth, Apple AirPlay 2, TV-remote operation, Trueplay room tuning, Speech Enhancement and Night Sound. Check Sonos’s US product listing for specifications and current price; availability and pricing can change, and prices differ by country.
What published reviews say about its sound
TechRadar reviewer Harry Padoan said he tested the Beam Ultra for a week in Future Labs’ TV testing space, watching movies and listening to music in Dolby Atmos and stereo. He praised its compact Atmos effects, dialogue and bass, while flagging its connection and format limitations. What Hi-Fi? also described it as strong for both movies and music. SoundGuys reported impressive movie sound and bass without a large footprint. Those are reviewers’ assessments under their respective conditions, not a guarantee of the same result in every room.
#1 Best Overall
- Enrich your entertainment experience with vibrant bass, crystal clear dialogue, and a panoramic soundstage.
- Experience a 3D surround sound effect with Dolby Atmos.
- Stream music, radio, podcasts, and audiobooks from all your favorite services when the TV is off.
- Control with the Sonos app, your TV remote, Apple AirPlay 2, and your voice.
- Effortless setup with only two cables and smart Trueplay tuning.
Sonos says the Beam Ultra’s redesigned center channel is intended to improve dialogue clarity and that Speech Enhancement offers four levels. The company also lists Night Sound, which is intended for quieter late-night listening. Those are manufacturer descriptions of features, not independent measurements of how much clearer dialogue will sound in a particular setup.
Where the Beam Ultra’s compromises matter
No DTS:X and no HDMI passthrough
TechRadar reports that the Beam Ultra does not support DTS:X and has no HDMI passthrough input. If you watch DTS:X discs or need to connect several HDMI sources directly to a soundbar, those omissions are significant. The Beam Ultra relies on HDMI eARC: connect compatible sources to the TV and send audio to the bar over eARC, if your television supports the formats and pass-through behavior you need. Check your TV and source-device manuals before buying; eARC does not add passthrough inputs to the soundbar.
Rank #2
- Enrich your entertainment experience with vibrant bass, crystal clear dialogue, and a panoramic soundstage.
- Experience a 3D surround sound effect with Dolby Atmos.
- Stream music, radio, podcasts, and audiobooks from all your favorite services when the TV is off.
- Control with the Sonos app, your TV remote, Apple AirPlay 2, and your voice.
- Effortless setup with only two cables and smart Trueplay tuning.
Compact does not mean a separate subwoofer is included
The Beam Ultra is sold as a soundbar, not a package with a separate subwoofer. SoundGuys’ reviewer found its bass impressive for a compact bar, but that judgment does not establish that it will satisfy listeners seeking deep, room-filling bass. Sonos says owners can expand the system with a Sub, but that is an additional purchase.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsUpward-firing Atmos depends on the room
The two upward-firing drivers are part of Sonos’s stated 7.1.2 design. Height effects depend on how sound reflects from the ceiling and on the room and seating arrangement; the specification alone cannot guarantee a convincing overhead impression in every space. Consider room shape and placement before treating the channel count as a promise of a particular listening result.
Rank #3
- Take your TV, music, and gaming to the next level with this compact smart soundbar and subwoofer.
- This set is ideal for smaller or medium-sized rooms and low to moderate volume levels.
- Use the Sonos app to easily set up your home theater system and sync with your existing TV remote.
- Sub Mini balances out the lowest frequencies so Beam sounds even better.
- When the TV is off, stream music and more over WiFi from hundreds of services using the Sonos app, your voice, and Apple AirPlay 2.
Beam Ultra versus other soundbar choices
These options serve different priorities; the Beam Ultra’s US price is listed by Sonos, while the comparison review describes features rather than establishing current prices for every model.
| Option | Configuration and connection details | Best fit to consider |
|---|---|---|
| Sonos Beam Ultra | Mid-size 7.1.2 Dolby Atmos bar, according to Sonos; $699 on Sonos’s US page as of October 4, 2026. No HDMI passthrough or DTS:X, according to TechRadar. | Buyers prioritizing a compact single-bar setup, Dolby Atmos and the option to expand within Sonos. |
| Samsung HW-Q800F | TechRadar describes a 5.1.2 multi-box system with a subwoofer, HDMI input/passthrough and DTS:X. Current price and package configuration: not stated in the cited review. | Buyers who prioritize an included subwoofer, DTS:X or HDMI input flexibility and can accommodate a larger setup. |
| Sonos Arc Ultra | Positioned above the Beam Ultra in the Sonos lineup by the cited reviews. Current price and full comparison specifications: not stated in the cited sources. | Buyers considering a larger Sonos bar; room fit and current price should be checked before comparing. |
| Bose Smart Ultra Soundbar | Included as an Atmos alternative in TechRadar’s comparison. Current price and detailed configuration: not stated in the cited review. | Buyers comparing another Atmos bar; verify current model details and price. |
TechRadar specifically presents the Samsung as an alternative for deeper bass and more connectivity, while noting its larger footprint. Compare current packages and prices directly: a bar-plus-subwoofer bundle is not equivalent to the Beam Ultra’s soundbar-only price.
Rank #4
- HEAR YOUR TV BETTER: Designed with simplicity in mind, the Bose TV Speaker is an all-in-one soundbar that clarifies speech and is a simple fix for better TV sound
- WIDE, NATURAL SOUND: 2 angled full-range drivers deliver a more realistic, spatial audio experience for overall better TV sound from a small soundbar
- ENHANCED DIALOGUE: This sound bar for smart tv is designed to specifically focus on clarifying and elevating vocals and pronunciation
- BLUETOOTH TV SPEAKER: Pair your device to this Bluetooth soundbar to wirelessly stream your favorite music and podcasts. Connect up to 3 devices through the inputs (HDMI, Optical in, and AUX in); the first powered on device will automatically connect
- SIMPLE SETUP: A single connection from this compact soundbar to the TV via an optical audio cable (included) or an HDMI cable (sold separately) has you up and running in minutes
Can you add a subwoofer or surrounds later?
Yes. Sonos says the Beam Ultra can be expanded with a Sub and compatible rear speakers, including some portable Sonos speakers. These are optional products, not included in the $699 soundbar listing, and additions increase the total cost. SoundGuys’ reviewer suggests adding surrounds before a Sub, but that is one reviewer’s preference rather than a universal upgrade order. Sonos also names a dedicated Beam Ultra wall mount; confirm its current availability and compatibility before purchase.
Who should buy the Beam Ultra?
- Consider it if you want a compact Dolby Atmos bar, value dialogue and music as well as movie playback, and may want to expand with Sonos speakers later.
- Look elsewhere if DTS:X playback, direct HDMI inputs or an included subwoofer are priorities. TechRadar’s Samsung comparison is a relevant alternative to investigate, with the trade-off of a larger footprint.
- Compare against Arc Ultra if you have room for a larger Sonos bar or are considering spending more. The Beam Ultra is not positioned as Sonos’s flagship, and the cited sources do not establish current comparative pricing.
On the evidence available, the Beam Ultra makes a strong case as a compact, expandable Atmos soundbar—not as a universal replacement for a flagship system. The headline’s personal swap claim cannot be verified from product specifications or outside reviews; a fair first-person verdict would require the author’s actual setup and listening experience.
