Sound Motion - Key to next-level immersion
Sound Motion™ technology redefines what’s possible in audio performance. By integrating Sound Motion™ into Arc Ultra, we’re able to obtain a deeper, more powerful bass response in a smaller package. This innovation frees up space for additional tweeter and midrange drivers, delivering a more expansive and balanced soundstage, surpassing the previous generation of Arc.
Beyond immersive
Pair Arc Ultra with a Sonos Sub and Era 300 rear speakers for the ultimate Dolby Atmos surround sound experience, with bass you can feel and jaw-dropping detail from every direction.2 Make the experience all your own with a pair of Sonos Ace headphones.

The Sonos Arc Ultra is Sonos' flagship smart soundbar, built around 15 class-D amplifiers driving seven silk-dome tweeters — two firing upward for genuine height channels — alongside six midwoofers and a four-motor, dual-membrane Sound Motion woofer that packs deep bass into a flat, compact design without a separate subwoofer. Together they create a 9.1.4 spatial audio experience with full Dolby Atmos support, going well beyond the height-channel virtualization used in smaller Sonos soundbars like the Beam. Advanced Speech Enhancement gives finer control over dialogue clarity than earlier Sonos models, and Night Sound mode compresses dynamic range for quieter late-night viewing. It connects via HDMI eARC for full-bandwidth Atmos passthrough, streams over Wi-Fi and Bluetooth, and responds to Sonos Voice Control or Amazon Alexa through its far-field microphone array. TV Audio Swap lets sound transfer instantly to Sonos Ace headphones for private listening, and Trueplay tuning calibrates output to the room. Available in black or white, it's built for anyone assembling a top-tier Dolby Atmos home theater around a single premium soundbar rather than the smaller Beam or entry-level Ray.
