The Arc Ultra is Sonos’s most capable soundbar, featuring the new Sound Motion woofer that replaces three conventional drivers with a single flat transducer — delivering dramatically deeper bass from the same form factor as the original Arc. Its HDMI eARC port is rated for HDMI 2.1 bandwidth at 48 Gbps, ensuring lossless Dolby TrueHD Atmos passthrough from any source. This is also the first Sonos soundbar with Bluetooth connectivity alongside Wi-Fi 6E. Like its predecessor, there’s no HDMI passthrough — every source must route audio through your TV first.
Sonos flagship Atmos soundbar with Sound Motion driver, HDMI 2.1 eARC, Wi-Fi 6E, and Bluetooth.
