Bring all your entertainment to life with breathtakingly realistic sound and the 3D experience of Dolby Atmos. 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. 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. Stream from all your favourite services, and feel like you're in the song with support for the highest-resolution formats, including Dolby Atmos Music. 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. Trueplay tuning technology adapts the sound for the unique acoustics of the room and calibrates the height channels for precise localisation. So your content always sounds just the way it should and reaches your ears at the exact right moment. 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. Mix and match speakers to build the sound system you want over time. Simply add on when you're ready and enjoy listening all around your home and beyond.
