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.

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.
