Our Verdict

Sonos Arc Ultra

Ultimea Skywave X100 Dual

The Sonos Arc Ultra and Ultimea Skywave X100 Dual are radically different soundbar systems. The Ultimea is a fully equipped 9.2.6-channel setup with two subwoofers and four satellites, while the Sonos Arc Ultra is a standalone 5.1.2-channel soundbar. As you'd expect, the more expansive Ultimea reproduces more bass and more convincing surround and height effects. That said, you may prefer the Sonos Arc Ultra if you intend to expand it with satellites or a subwoofer, especially if you already own compatible Sonos speakers.
