Sonos Arc Ultra Black: Spatial Audio Flagship for Cinematic Home Theater

The Sonos Arc Ultra Black is a state-of-the-art soundbar that transforms your living space with extraordinary immersive sound. Designed for large rooms and the most demanding TV setups, this model employs a 9.1.4 Dolby Atmos system with cutting-edge Sound Motion™ technology. Effects, dialogue, and music are precisely positioned in three dimensions, so every detail envelops the listener. Serving as Sonos' most advanced soundbar, it also functions as a powerful multi-room music speaker, streaming over WiFi or Bluetooth, and can be controlled via app, remote, or by voice. Every element—from the curved, low-profile design to the intuitive setup—has been engineered for performance and daily convenience.

Next-Generation Features Elevate Every Scene

What distinguishes the Arc Ultra is its Sound Motion™ woofer, a flat, four-motor, dual-membrane innovation that delivers exceptional bass in a compact format. Fourteen total drivers, including nine precisely angled silk-dome tweeters, surround listeners with clear highs and dedicated height channels for authentic spatial audio. Speech Enhancement powered by Sonos’ AI improves dialogue clarity, while Trueplay™ room calibration tailors the sound to your space.
