At 46.18 inches wide, the Arc Ultra is the widest bar in this group, and that's the first thing to check against your TV stand. The 9.1.4 channel count is the other headline: Sonos uses its Sound Motion architecture to place height and rear effects without adding satellite speakers.
We tested it with movie soundtracks that lean on overhead effects, and the bar does more with a single box than most of the front-stage systems here. The effect is not the same as discrete rear speakers, but it's the most convincing single-bar Atmos bubble in this set. Dialogue is the practical win: the AI Speech Enhancement lifts voices without making the rest of the mix sound hollow.
The touch controls on top are a useful fallback when the remote is across the room, and the bar's 3.13-inch height keeps a low profile under the screen. It is still a wide piece of furniture, so a 55-inch TV on a narrow stand may leave the ends hanging over the edge.
Bass is handled by the bar alone, and Sonos sells the Sub 4 separately. The bar's low end is balanced rather than thunderous, so if you want chest-thump, budget for the extra box. That's a real cost, but it keeps the footprint to one piece and avoids another wireless pairing step.
If you want the most convincing single-bar Atmos effect here and can give it the width, the Arc Ultra is our top pick. If you need more bass for the money, the JBL Bar 500MK2 is the better fit; if space is tight, the Samsung S60D makes more sense.
Pros
- Most convincing single-bar Atmos effect in this set
- Speech enhancement keeps dialogue clear
- Slim 3.13-inch profile with touch controls
- Streaming and TV control are well covered
Cons
- No subwoofer included
- 46-inch width needs a wide stand
We recommend the Arc Ultra for the most convincing single-bar Atmos experience here, provided your TV stand can handle its 46-inch width.
