Our Verdict

Bose Solo 5

Polk Audio Signa S2

The Polk Audio Signa S2 is a better soundbar than the Bose Solo 5. The Polk has a better overall sound, and its dedicated wireless subwoofer provides more bass. It can get noticeably louder and supports audio formats over ARC. However, the Bose feels more premium and is shorter, which makes it a better option if you're looking for a compact soundbar.
