Our Verdict
Sonos Arc Ultra
Sonos Ultimate Immersive Set with Arc Ultra
While the Sonos Ultimate Immersive Set with Arc Ultra is better than the all-in-one Sonos Arc Ultra, they share virtually the same features. The key improvements that the added satellites and outboard subwoofer included in the Ultimate Immersive Set with Arc Ultra offer are a more immersive Dolby Atmos and surround sound experience, alongside greater bass extension. However, if you're short on space, the all-in-one Arc Ultra outputs an impressive stereo soundstage on its own and still provides an alright Atmos experience, considering it lacks drivers situated behind you.
