Description

The Sonos Arc Ultra is a premium Dolby Atmos soundbar built for large TVs, living rooms, media rooms, and wireless home cinema setups where a single speaker needs to deliver serious scale. Its sleek low-profile design keeps the setup clean, while its wide soundstage helps movies, shows, games, and music feel more spacious and engaging.

Arc Ultra uses Sonos Sound Motion technology and an all-new 14-driver acoustic architecture to create a powerful 9.1.4 spatial audio experience. Dolby Atmos support adds height, depth, and movement to soundtracks, while improved bass performance gives action scenes and music more weight without needing a bulky speaker system upfront.

For everyday use, the Sonos Arc Ultra supports HDMI eARC, Wi-Fi, Bluetooth, Apple AirPlay 2, Trueplay tuning, Speech Enhancement, Night Sound, voice control, and app-based control. It can be used as a standalone soundbar or expanded with Sonos Sub and Era 300 rear speakers for a more immersive wireless surround sound system.
