Sonos Arc Ultra Black
Sonos's flagship soundbar: 1.18 m and fifteen amplifiers, nine silk-dome tweeters — two of them firing at the ceiling — and Sound Motion, a dual-membrane woofer with four motors that delivers subwoofer bass from a 7.5 cm tall body.
Why people like it
- Sound Motion — the woofer Sonos redesigned from scratch to give real bass with no cabinet depth.
- Two up-firing tweeters — the Dolby Atmos height channel comes from bouncing sound off the ceiling.
- AI Speech Enhancement — it detects the human voice and lifts it, with four levels in the app.
- Trueplay on iPhone and Android — it measures the room on either.
