Samsung HW-Q990F vs Sonos Arc Ultra
Which should you buy? Here's the honest call, pulled from our full The Best Premium Dolby Atmos Soundbars: 4 Compared (and One to Skip) comparison.
For the fullest home-theater effect out of the box, the Samsung HW-Q990F's real rears and subwoofer make it the most immersive package for the money. If you'd rather have one beautiful bar you can grow later, the Sonos Arc Ultra is the premium all-in-one to beat.

Samsung HW-Q990F
Buy itThe most complete Atmos package in a box - real rears, a real sub, and a huge 11.1.4 bubble of sound.
- Ships as a full 11.1.4 system with wireless rear speakers and a subwoofer, so it delivers true surround with no add-ons
- Independent testing praises its immersive, dynamic height effects and newly redesigned, more controlled bass
- Feature-loaded: dual HDMI 2.1 4K/120Hz passthrough for consoles, plus Q-Symphony pairing with Samsung TVs
- It's a lot of hardware - four pieces to place, power and hide cables for
- Owners note it leans cinematic; stereo music is good rather than class-leading

Sonos Arc Ultra
Buy itThe premium single-bar Atmos experience - gorgeous, effortless, and it grows into a full system when you're ready.
- Reviewers report the widest, most convincing height and soundstage of any all-in-one bar, thanks to its new sound-motion woofer
- Genuinely excellent with music, not just movies - owners note it holds up as a standalone streaming speaker
- Clean single-bar install with room-tuning (Trueplay) and the option to add a Sonos sub and rears later
- No discrete surround or subwoofer in the box, so out-of-box bass and rear effects trail the full multi-piece systems
- No HDMI passthrough - a single eARC port means it can't sit between your console and TV for 4K/120Hz
