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.
Speech Enhancement, powered by AI, detects the human voice to clarify dialogue, giving you greater control so you never miss a word. Quickly set up Arc Ultra with the included HDMI cable, and enjoy streamlined control with your TV remote. You can also use the Sonos app, the touch controls on top of the soundbar, Sonos Voice Control, and Amazon Alexa.
When your TV is off, stream music and more from all your favourite services using WiFi and Bluetooth. Add a Sonos Sub and Era 300 rear speakers for the ultimate Dolby Atmos surround sound experience. Listen all around your home when you add Sonos speakers to other rooms.
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.
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.
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.
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.
Instantly swap TV audio from Arc Ultra to Sonos Ace for private surround sound and sensational spatial audio with dynamic head tracking. Connect two Sonos Ace headphones at once to enjoy a movie with a companion or immerse yourself in couch co-op gaming.
TrueCinema technology with Arc Ultra enhances your Sonos Ace headphones by precisely mapping your space, then virtually rendering the most lifelike surround sound experience. You’ll feel like you’re listening out loud in your own private theatre.
Get theatre-quality sound in minutes. Simply plug in the power cable, connect your TV with the included HDMI cable, and open the Sonos app to complete setup.
With just a few taps in the Sonos app, Trueplay™ optimizes the sound for the unique acoustics of the room and placement of the soundbar. Available for iOS and Android.
