- 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.
