Cinematic sound
Surround yourself in the story
Dolby Atmos maps sounds in space for a 3D effect so you experience planes as if they're flying overhead, hear footsteps moving across the room, and feel the score all around you. Requires a TV that supports Dolby Atmos and Atmos-encoded content.
Heighten your home theater experience
Featuring eleven precisely engineered internal speakers, including two dedicated height channels, Arc fires sound in all directions, rendering every whisper, explosion, and beat with dramatic clarity, detail, and depth.
Never miss a word
Fine-tuned by Oscar-winning sound engineers, Arc offers crystal clear dialogue so you can always follow the story. For even greater clarity when characters whisper or the action intensifies, turn on Speech Enhancement in the Sonos app.
Get immersed in music
Stream from all your favorite services, and feel like you're in the song with support for the highest-resolution formats, including Dolby Atmos Music. Dolby Atmos Music requires a compatible streaming service.
Simply beautiful
With only two cables and step-by-step guidance in the Sonos app, Arc is easy to set up, and the elegant design fits seamlessly into your home, whether you place it on furniture or mount it to the wall.
Tuned to perfection
Trueplay tuning technology adapts the sound for the unique acoustics of the room and calibrates the height channels for precise localization. So your content always sounds just the way it should and reaches your ears at the exact right moment. Requires an iOS device.
Surround sound, simplified
Get an even more immersive experience with a subwoofer and rear speakers. Everything connects quickly and easily over WiFi so you don’t have to run wires across the room.
Better together
Mix and match speakers to build the system you want. Enjoy listening all around your home, and reconfigure your setup any time.
