Sonos Arc Ultra
Sound beyond surround
The Sonos Arc Ultra is a flagship Dolby Atmos soundbar designed to transform movies, music and gaming with immersive 9.1.4 spatial audio. Sound Motion™ technology delivers powerful bass from an elegant low-profile design, while Trueplay tuning, AI-enhanced dialogue and seamless Sonos integration create a refined premium home cinema experience.
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.
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 mid-range drivers, delivering a more expansive and balanced soundstage, surpassing the previous generation of Arc.
