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 sound all around you for an entertainment experience that feels out of this world. Experience clearer dialogue, deeper bass, and more detailed sound that precisely surrounds you from every direction — all in an unbelievably sleek design. Dolby Atmos takes immersion to a whole new dimension, creating a 9.1.4 spatial audio experience. An advanced version of Speech Enhancement gives you greater control over dialogue clarity, so you never miss a word. Get set up in minutes 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 Arc Ultra, Sonos Voice Control, and Amazon Alexa. When your TV is off, stream music and more from all your favorite services using Wi-Fi 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 Sono's speakers to other rooms.
