The Arc Ultra is Sonos' best soundbar and its flagship speaker

The Arc Ultra is Sonos' best soundbar speaker, replacing last year's Arc model. It is a massive 46" soundbar that houses 14 total speakers, including five tweeters (plus two upward-firing speakers for Dolby Atmos supported height channels), six midwoofers, and a four-motor, dual-membrane Sound Motion woofer. The Arc Ultra uses AI enhancement technology to isolate and boost the clarity of dialogue and voices. It also has a built-in microphone so that it can be controlled using voice commands from the Sonos app or your favorite smart assistant. Check out our own Sonos Arc Ultra review.

The Arc Ultra and Sub 4 are the perfect Dolby Atmos matchup

The audio savvy knows that a single speaker isn't enough to reproduce an entire soundstage. If you could pick only one other speaker, then a subwoofer would make the most meaningful impact. Given how the Arc Ultra excels at the highs and mids, the subwoofer addition would be a no-brainer. The Sub 4 features dual inward-facing 5"x8" woofers and a traditional ported design that allows for a louder and deeper low-end. It also has much more power than the Sub Mini and can reverberate the walls of any sized room in your house. There's no better complement to the Arc Ultra.
