A head-to-head soundbar comparison to help you pick the right one for your room.
Updated August 20, 2026
Verdict
These are not really the same product. The Samsung is a full 11.1.4 system with wireless rears and a subwoofer, and it genuinely produces surround. The Sonos is a single compact bar that virtualises height and surround from one box. Buy the Samsung if you want real surround without running cables; buy the Sonos if space and simplicity matter more.
| Samsung HW-Q990D | Sonos Beam Gen 2 | |
|---|---|---|
| Configuration | 11.1.4 with rears and sub | Single bar, virtualised |
| Real surround | Yes, discrete rear speakers | Simulated |
| Subwoofer | Included | Optional extra |
| Room footprint | Bar, sub and two rears | One bar |
| Price | Much higher | Much lower |
| Best for | Dedicated film watching | Small rooms, simplicity |
You want the surround effect to actually come from behind you and you do not want to run speaker cable. This is about as close to a discrete system as a soundbar package gets.

The room is small, the television is in a living space, or you want one tidy box that meaningfully improves TV audio without dominating the room.

It can decode it and steer sound, but a single box cannot place a sound behind you the way a rear speaker does. Virtual height and surround are real effects, just weaker ones.
No, but it is far tidier. A receiver with real speakers outperforms any soundbar at the same total price. The soundbar wins on cables, space and domestic acceptance.
For film, yes. Most of what makes a soundbar sound thin is missing bass, and no amount of processing replaces a driver moving air.
