Sonos Arc Ultra vs Bose Lifestyle Ultra Soundbar

The Sonos Arc Ultra is the stronger single-bar pick for most people: a 9.1.4 layout, 14 drivers and 15 amps, and a mature app. The Bose Lifestyle Ultra Soundbar is the better value right now at $899.00 as of November 5, versus $989.10 for the Arc Ultra at its lowest since October 28. Buy the Bose if you want Atmos for less and a display screen; buy the Sonos if you plan to add a Sub and rear speakers later.

Questions and answers

Which is better for Dolby Atmos?
The Sonos Arc Ultra. Its 9.1.4 layout with up-firing and side-firing drivers is the more explicit Atmos design. The Bose supports Atmos but does not publish its channel count.
Is the Sonos worth about $90 more?
Yes if you want the deepest bass from a single bar and a path to Sub and Era 300 rears. If you just want Atmos on a budget, the Bose at $899.00 as of November 5 is the better deal.
Which has better bass without a subwoofer?
The Sonos Arc Ultra, thanks to its Sound Motion dual-membrane woofer. Bose does not publish comparable bass specs, so add its bass module if low end matters.
Which has more connections?
The Bose. It adds USB, AUX and RCA on top of HDMI, Ethernet, Bluetooth and Wi-Fi. The Sonos covers HDMI eARC, Ethernet, optical, Bluetooth and Wi-Fi.
Can both be expanded to full surround?
Yes. Sonos takes a Sub and Era 300 rear speakers; Bose takes its own surround speakers and bass module. Both add cost.
Which is easier to set up?
Both rely on their apps. Sonos reviewers praise the improved app setup; the Bose display helps confirm inputs without opening an app.
