Main trade-off
Samsung HW-Q990F
Both rear speakers still need electrical power.
Head-to-head
Samsung Q990F vs Q800F: Q990F includes rears and passes 4K120, Q800F sends a 120Hz console to the TV
The short answer
Choose Q990F if you want rear speakers included or need two 4K 120 Hz sources through the bar. Choose Q800F if a bar and subwoofer are enough and you want fewer speakers to place. Its one HDMI input is limited to 4K 60 Hz, so connect a 120 Hz console to the TV instead.
Before you choose
The reasoning and the trade-offs
Q800F can still work with a 120 Hz TV
Connect the console to a suitable TV HDMI input and return compatible audio over eARC.
What this is based on
The 60 Hz limit applies to video passed through the Q800F input. It does not turn every other TV input into a 60 Hz input.
Main trade-off
Samsung HW-Q800F
Rear speakers are not included.
Samsung HW-Q990F
- Choose it for
- You want physical rear speakers included immediately.
- Two 4K 120 Hz sources need direct soundbar connections.
- Main trade-off
- Both rear speakers still need electrical power.
Samsung HW-Q800F
- Choose it for
- You do not want separate rear speakers today.
- A 43.73-inch bar fits where a 48.5-inch bar will not.
- Main trade-off
- Rear speakers are not included.
About this comparison
Compare Q990F and Q800F by rear-speaker placement, HDMI bandwidth and cabinet size. See why two 120 Hz consoles change the recommendation.
Rear-speaker placement and the HDMI signal path matter more than comparing the two channel numbers in isolation.

What matters in practice
The differences that matter
Q800F can still work with a 120 Hz TV
Connect the console to a suitable TV HDMI input and return compatible audio over eARC.
How we reached this conclusion
The 60 Hz limit applies to video passed through the Q800F input. It does not turn every other TV input into a 60 Hz input.
The smaller package keeps the same compact subwoofer footprint
Both listed subwoofer cabinets are approximately 9.8 inches wide and deep.
How we reached this conclusion
The Q800F space saving comes mainly from a smaller bar and no supplied rear speakers, not from halving the bass-box footprint.
Removing two rear speakers removes two placement decisions
Q800F needs positions for the bar and subwoofer. Q990F also needs two powered rear locations.
How we reached this conclusion
Wireless audio links do not eliminate electrical power requirements, so a sofa in the middle of the room may change the recommendation.
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.
Samsung HW-Q990F
Does not meet these checksIt needs 48.5 inches of width, more than your 48 inches.
Samsung HW-Q800F
Meets these checks43.73 inches wide and 2.38 inches high, with 1 separate HDMI source input. It leaves 4.3 inches of total spare width.
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.
Choice A
Samsung, HW-Q990F/ZA
Samsung HW-Q990F

Meaningful differences
What changes the fit
| What changes | Samsung HW-Q990F | Samsung HW-Q800F | Why it matters |
|---|---|---|---|
| Package | 11.1.4 with subwoofer and rears | 5.1.2 with subwoofer, no rears | Q990F includes hardware behind the listener. |
| HDMI source inputs | 2 | 1 | Q990F handles one more source directly. |
| Confirmed 4K passthrough | 120 Hz | 60 Hz | A 120 Hz console should bypass the Q800F video input. |
| Cabinet width and height | 48.5 × 2.79 inches | 43.73 × 2.38 inches | Q800F saves both width and screen clearance. |
| Subwoofer cabinet footprint | About 9.8 × 9.8 inches | About 9.8 × 9.8 inches | The smaller soundbar package does not also shrink the subwoofer floor footprint. |
