Sonos Beam Ultra at $699 Brings True 7.1.2 Atmos With Up-Firing Drivers
Sonos has priced the Beam Ultra at $699 with dedicated upward-firing drivers for Dolby Atmos. The bar handles Atmos with separate height hardware instead of relying only on software to simulate overhead sound. Engadget
Sonos lists the output as true 7.1.2 Dolby Atmos sound. That notation means seven ear-level channels, one low-frequency channel for bass, and two separate height channels. Sonos
The bar uses nine custom drivers in total, five tweeters for high frequencies and four woofers for midrange and bass. Two of those tweeters fire upward and are assigned to the height channels. Engadget
Each driver has its own amplifier, nine drivers and nine amplifiers. Each driver also gets its own digital signal processing path, which lets Sonos set volume, timing, and tuning for each speaker on its own without the compromises of a shared passive crossover.
The Beam Ultra is 2.5 inches tall and weighs 6.35 pounds. Sonos calls it a mid-size soundbar and positions it for TVs up to 65 inches. Sonos
The difference from the second-generation Beam is physical, not only software. That older model used processing and beam steering to suggest sound from above. The Beam Ultra adds two physical up-firing tweeters that bounce sound off the ceiling, much as a lamp pointed upward spreads light by reflection. In a rectangular room with a flat 8 to 10 foot ceiling, that is a different acoustic method.
Voice control stays built in. The bar includes a far-field microphone that can hear commands from across the room and works with both Amazon Alexa and Google Assistant. That keeps hands-free control in the TV area without adding a separate smart speaker. Engadget
The $699 price sits between current Sonos tiers. The second-generation Beam costs $499, the original Arc cost $799, and the Arc Ultra launched at $999 and now sells for $1,099. Engadget
That is a $200 step up from the Beam Gen 2. The extra cost covers the physical height drivers, a higher driver and amplifier count, and native 7.1.2 decoding. For buyers, the comparison is between hardware that directs sound overhead and processing that creates a sense of height.
Sonos introduced the Beam Ultra alongside the Sonos Ace Ultra. Preorders opened Sept. 1, with general availability and shipping starting Sept. 29, 2026. Gear Patrol
The broader context here is familiar from past compact home theater gear. A small bar can decode height information correctly and still have trouble keeping overhead sounds separate from ear-level sound in a real living room. Ceiling height, ceiling material, seating distance, and where the bar sits in its cabinet still shape the result.
In my view, the one-amplifier-per-driver design matters as much as the two extra tweeters. It gives Sonos the headroom and fine-grained calibration to keep dialogue clear when height effects are active. The 65-inch guidance is practical, not a hard limit. It reflects output and soundstage width from a compact cabinet, so a larger room or a longer distance to the couch will still favor the Arc Ultra tier even when the channel numbers look similar.
