Our take on the Polk Audio SIGNA S2D Sound Bar and Wireless Subwoofer with Dolby Atmos (2025)

The Polk Audio SIGNA S2D is a 2.1-channel sound bar with a wireless subwoofer and Dolby Atmos support. It aims to add height and bass to TV sound without a full surround setup, and it connects over HDMI, optical, AUX, Bluetooth and Ethernet. Against Atmos rivals it is a modest 2.1 design, so height effects are simulated rather than delivered by up-firing drivers. It suits small to mid-size rooms where a single bar plus sub is enough.

Pros
  • Wireless subwoofer adds real low-end without extra cables
  • Dolby Atmos decoding for height-aware soundtracks
  • Wide input set: HDMI, optical, AUX, Bluetooth, Ethernet
  • Wall-mountable and simple to place
  • 2.1 setup is easier to fit than a full surround system
Cons
  • 2.1 channels only, so Atmos height effects are limited
  • 40 W total is modest for large or open rooms
  • No dedicated up-firing drivers for overhead sound
  • Fewer channels than multi-speaker Atmos bars at similar levels

Questions and answers

Does the SIGNA S2D produce real overhead Atmos sound?
It decodes Dolby Atmos and spreads height cues through the bar, but with 2.1 channels and no up-firing drivers the effect is simulated. Expect a wider front stage rather than sound from the ceiling.
What is included in the box?
The sound bar, the wireless subwoofer, a remote and power cables. Check the listing for the specific HDMI or optical cable, since those are often not included.
Can I wall-mount the sound bar?
Yes. The bar is designed for shelf or wall placement, and the subwoofer only needs a power outlet nearby since it connects wirelessly.
How do I connect it to a TV?
Use HDMI if your TV has an ARC or eARC port for one-cable control. Optical or AUX works for older TVs, and Bluetooth handles phone streaming.
Is 40 W enough for a living room?
It is fine for small to mid-size rooms at normal listening levels. Large or open spaces with high ceilings will want a more powerful multi-channel bar.
Does it support a surround setup with rear speakers?
No. It is a 2.1 system, so there are no rear channels or add-on surrounds. For true surround you need a bar with separate rear speakers.
