The Sonos Arc Ultra is the soundbar most home theater reviewers now use as the reference point for everything else. Its 14-driver array, new Sound Motion woofer, and 9.1.4 Atmos rendering deliver one of the widest, deepest one-piece performances on the market, and the Sonos app and ecosystem make day-to-day living with it genuinely pleasant. It is not the absolute loudest or the most format-complete bar you can buy, but for most living rooms it represents the cleanest balance of sound, design, and software.
- — 9.1.4 Dolby Atmos rendering with 14-driver array sets a new benchmark for one-piece soundbars
- — New Sound Motion woofer roughly doubles the bass output of the original Arc without a separate sub
- — Single HDMI eARC port limits direct device input compared to multi-HDMI rivals
- — No DTS:X support, which still matters for some Blu-ray libraries
