The catch
Sonos Arc Ultra
Separate HDMI inputs are missing, so a console or disc player cannot plug in.
Side by side
Sonos Arc Ultra vs Samsung Q990F: Samsung packs in surround speakers, Sonos begins as one bar plus extra spending
Quick verdict
If you have room and outlets for two rear speakers, go with the Q990F. The subwoofer and rears come with it, and it takes two 4K 120 Hz sources. The Arc Ultra is the better pick when you would rather start with one bar and grow a Sonos system over time, but its price leaves out the extra speakers.

How we worked this out
Put the exact compatible Sonos accessories in the cart before you compare totals. Either product works without them, but the layouts you end up with are different.
Two inputs on the bar can relieve a genuine TV bottleneck
On a four-HDMI TV, eARC uses up a port and three TV inputs remain. Add the Q990F and two more sources can plug into the bar.
How we worked this out
Count three leftover TV inputs and two on the soundbar and you get five physical source connections, against three with the Arc Ultra. The count does not mean every TV port handles the same video mode.
The saving in console width is small
At about 4.4% narrower, the Arc Ultra is slimmer than the Q990F.
How we worked this out
Work it out as (48.5 − 46.38) ÷ 48.5. Pick the Sonos for its single-bar layout or its ecosystem. It is not dramatically smaller across the TV stand.
Plug in your numbers
Is there room for the soundbar under your TV?
Measure the clear space under your TV. Count only the devices you will plug into the soundbar. Leave out the ones already connected to the TV. The numbers below are placeholders until you enter yours.
Sonos Arc Ultra
Fails these checksWith 0 separate HDMI source inputs, it cannot take the 1 device you want to plug into the bar.
Samsung HW-Q990F
Fails these checksIt takes 48.5 inches of width, more than your 48 inches.
Measure the top of an open shelf. This check does not cover enclosed cubbies. Detachable speakers count toward the docked width. Leave extra depth for cables and the TV stand. This checks size and port count only. Dolby Atmos, 4K/120Hz passthrough and the audio formats your TV supports are outside it.
Option A

Option B
Samsung, HW-Q990F/ZA
Samsung HW-Q990F

Spec by spec
Where they really differ
| Spec | Sonos Arc Ultra | Samsung HW-Q990F | In practice |
|---|---|---|---|
| What arrives | Soundbar only | Bar, subwoofer and two rears | With Samsung, the speakers behind the sofa are physical and in the package. Sonos needs a separate purchase to get that layout. |
| HDMI source inputs | 0 | 2 with 4K 120 Hz passthrough | Two sources can plug into the Samsung instead of crowding the TV’s connection panel. |
| Cabinet width | 46.38 inches | 48.5 inches | Bar width is only 2.12 inches less on the Arc Ultra. The bigger difference in space comes from the extra floor and rear-speaker placement. |
| Height presentation | Upward-firing drivers in the bar | Height speakers in the bar and rear units | Samsung includes the rear height hardware. The standalone Arc Ultra does not. |
| Subwoofer floor space | No external subwoofer included | 9.8 × 9.8-inch subwoofer cabinet | Even before you add placement clearance, Samsung needs another powered position on the floor. |
Trade-offs
What each pick costs you
With Sonos Arc Ultra

- The bar measures 48.5 inches across.
Decision guide
How to decide
A price difference is not a system-cost difference
If you also want a subwoofer and rear speakers, putting the Arc Ultra’s price next to the Q990F’s is not a fair comparison. Add the exact compatible Sonos accessories first, then compare checkout totals. You can use either product without those extras, but the layouts that result are different.
Two inputs on the bar can relieve a genuine TV bottleneck
On a TV with four HDMI ports, eARC claims a port and leaves three TV inputs. The Q990F lets two more sources plug into the bar itself, so three TV inputs plus two soundbar inputs add up to five physical source connections. The Arc Ultra gives you three. Keep in mind that this count does not guarantee every TV port supports the same video mode.
The saving in console width is small
Measured across, the Arc Ultra is about 4.4% narrower than the Q990F. The calculation is (48.5 − 46.38) ÷ 48.5. Pick the Sonos for its single-bar layout or its ecosystem. Do not expect a dramatically smaller footprint on the TV stand.
What this page can’t tell you
- This comparison rests on manufacturer specifications and package contents rather than a controlled listening test. How a bar sounds also depends on room shape, placement and source content.
