Polk Audio Signa S2 — best budget sound bar for TV review 2026

Our assessment

The Signa S2 is built around the idea that you shouldn't have to choose between affordability and a complete sound system. The ultra-slim soundbar sits neatly under most TVs, and the wireless subwoofer connects without running cables across the room. VoiceAdjust lets you boost dialogue independently of the overall volume — useful for content with heavy background music or effects. HDMI, optical, and Bluetooth connectivity cover most setup scenarios. It's not a Dolby Atmos system, and the two-piece setup requires slightly more effort than an all-in-one bar, but the overall value proposition is hard to beat at this price.

The Polk Audio Signa S2 delivers strong value by pairing a slim soundbar with a wireless subwoofer at a price that undercuts many competitors. VoiceAdjust technology keeps dialogue clear while the subwoofer adds genuine low-end weight to movies and music.

Pros

  • Wireless subwoofer included — genuine low-end performance without cable runs
  • Strong value for a two-component soundbar system
  • VoiceAdjust technology enhances dialogue clarity independently
  • Multiple connection options: HDMI, optical, and Bluetooth
  • Ultra-slim soundbar design fits neatly under most TVs

Cons

  • Two-component setup requires slightly more effort than an all-in-one soundbar
  • Does not support Dolby Atmos — not a premium surround sound system

Bottom line

Polk Audio Signa S2 Ultra-Slim Sound Bar

The best value pick if you want a complete soundbar-plus-subwoofer system without paying premium prices. The wireless subwoofer and VoiceAdjust make a meaningful difference for everyday TV watching and movie nights.
