Sound Motion Technology Redefines Bass
The Arc Ultra's patented Sound Motion technology uses a dual-membrane woofer — not a traditional cone — to push air without the distortion of a conventional driver. The result is deeper, cleaner bass from an impossibly slim 75mm profile.
9.1.4 Dolby Atmos and Spatial Audio
Fourteen Sonos-engineered drivers — nine silk-dome tweeters, six midwoofers, and a Sound Motion woofer — fill your room from every direction. Objects overhead, sounds sweeping side to side, dialogue pinned precisely where it belongs. Powered by fifteen Class-D digital amplifiers.
Speech Enhancement with AI
Voices always stay clear, even in the most action-packed scenes. Sonos Speech Enhancement uses AI to isolate dialogue and elevate it above the mix — without touching the rest of the soundtrack.
Effortless Setup and Calibration
Connect via HDMI eARC to your TV. Trueplay uses the microphones on your iPhone to measure your room acoustics and tune the Arc Ultra precisely to the shape, furniture, and surfaces in your space.
WiFi 6 and Apple AirPlay 2
Stream losslessly from any source over WiFi 6. AirPlay 2 lets you control Arc Ultra from your iPhone, iPad, or Mac. Add a Sonos Sub and Era 300s for a true surround system — one app controls everything.
