The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Polk Signa S2 is the value benchmark in the sub-$200 soundbar tier. RTINGS, the highest-trust source in this pool, highlights its better overall sound and the deeper bass delivered by its dedicated wireless subwoofer, noting it can get noticeably louder and supports more audio formats than thinner all-in-one bars. That technical read is backed by an unusually large body of verified-purchase feedback, nearly 22,000 Amazon ratings averaging 4.4, which is a strong signal even after accounting for the gameability of star averages.
What reviewers liked
- RTINGS (high-trust) cites better overall sound and more bass thanks to the included wireless subwoofer
- Massive verified-purchase base (nearly 22,000 Amazon ratings at 4.4) corroborates real-world satisfaction
- Specialist r/Soundbars threads repeatedly rank it above pricier competitors in its bracket
- VoiceAdjust dialogue enhancement and easy plug-and-play setup praised across reviewers
Where it falls short
- Reviewers note a V-shaped sound signature that isn't equally comfortable across all genres
- No Dolby Atmos or height channels, so it can't match immersive bars
- Community members say its value erodes at full price versus sale pricing
- Design and feature set are dated compared with newer Atmos models

Specialist-community sentiment reinforces the picture: r/Soundbars threads repeatedly describe it outperforming pricier rivals in its bracket, with several users saying it bettered soundbars costing far more, and praising its five full-range drivers and VoiceAdjust dialogue boost. The recurring caveats are that it leans on a V-shaped (bass-and-treble-forward) signature that isn't ideal for every genre, and that some community members feel Polk's value proposition slips at full retail price versus on-sale pricing.
The consensus is that for a complete soundbar-plus-subwoofer system at this price, the Signa S2 remains hard to beat for movies and TV, even if audio purists and Atmos seekers will want to spend more.
