Head-to-head
Sonos Arc Ultra vs Samsung Q990F: Samsung includes surround speakers, Sonos starts with one bar and extra costs
The short answer
Choose the Q990F if you can place and power two rear speakers. It includes the subwoofer and rears and accepts two 4K 120 Hz sources. Choose the Arc Ultra if you want one bar now and prefer to build a Sonos system later. Its price does not include the extra speakers.
Before you choose
The reasoning and the trade-offs
The price gap is not the system-cost gap
An Arc Ultra price cannot be compared fairly with the Q990F price if you also want a subwoofer and rear speakers.
What this is based on
Add the exact compatible Sonos accessories before comparing checkout totals. Both products can be used without those purchases, but the resulting layouts differ.

What matters in practice
The differences that matter
The price gap is not the system-cost gap
An Arc Ultra price cannot be compared fairly with the Q990F price if you also want a subwoofer and rear speakers.
How we reached this conclusion
Add the exact compatible Sonos accessories before comparing checkout totals. Both products can be used without those purchases, but the resulting layouts differ.
Two source inputs can solve a real TV bottleneck
A four-HDMI TV leaves three TV inputs after eARC. With the Q990F, two additional sources can plug into the bar.
How we reached this conclusion
Three remaining TV inputs plus two soundbar inputs gives five physical source connections, versus three with the Arc Ultra. This count does not guarantee every TV port supports the same video mode.
Only a small amount of console width is saved
The Arc Ultra is about 4.4% narrower than the Q990F.
How we reached this conclusion
The calculation is (48.5 − 46.38) ÷ 48.5. Choose the Sonos for its single-bar layout or ecosystem, not because it is dramatically smaller across the TV stand.
Try your real numbers
Will the soundbar fit under your TV?
Measure the clear space in front of your TV. Count devices you want to plug into the soundbar, not devices already connected to the TV. The numbers below are examples until you enter yours.
Sonos Arc Ultra
Does not meet these checks0 separate HDMI source inputs cannot take the 1 device you want to connect to the bar.
Samsung HW-Q990F
Does not meet these checksIt needs 48.5 inches of width, more than your 48 inches.
Use an open top surface, not an enclosed cubby. Detachable speakers are counted in the docked width. Allow extra depth for cables and the TV stand. This checks physical dimensions and port counts, not Dolby Atmos, 4K/120Hz passthrough or your TV’s audio-format support.

Meaningful differences
What changes the fit
| What changes | Sonos Arc Ultra | Samsung HW-Q990F | Why it matters |
|---|---|---|---|
| What arrives | Soundbar only | Bar, subwoofer and two rears | Samsung supplies physical speakers behind the sofa. Sonos requires a separate purchase to reach that layout. |
| HDMI source inputs | 0 | 2 with 4K 120 Hz passthrough | The Samsung can take two sources away from the TV connection panel. |
| Cabinet width | 46.38 inches | 48.5 inches | The Arc Ultra saves only 2.12 inches of bar width. The larger space difference is the extra floor and rear-speaker placement. |
| Height presentation | Upward-firing drivers in the bar | Height speakers in the bar and rear units | Rear height hardware is included with Samsung, not with the standalone Arc Ultra. |
| Subwoofer floor space | No external subwoofer included | 9.8 × 9.8-inch subwoofer cabinet | Samsung needs another powered floor position before adding placement clearance. |
