Key Features

The soundbar, reinvented

Arc Ultra is the sleekest and most powerful soundbar Sonos has ever created. With an all-new acoustic architecture powered by 14 Sonos-engineered drivers and advanced technologies like Sound Motion™, Arc Ultra fills every inch of the room and precisely places sounds all around you for an entertainment experience that feels out of this world. 

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.

Dolby Atmos

Sound in a whole new dimension

With Dolby Atmos, Arc Ultra brings sound to life with sensational definition and envelops you in a mind-blowing 9.1.4 spatial audio experience.¹ 

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. Make the experience all your own with a pair of Sonos Ace headphones.

Dialogue has never been so clear 

Speech Enhancement with Arc Ultra uses AI to detect the human voice and clarify dialogue. With four customizable levels, you can ensure every listener hears every word with precision.
