Our Verdict
JBL Bar 5.1 Surround
Polk Audio Signa S4
The JBL Bar 5.1 Surround is a bit better for mixed usage than the Polk Audio Signa S4. The JBL is a 5.1 setup with a better surrounds performance. It can reproduce a more extended low-bass, and it also comes with more sound enhancement features, including room correction. That said, the Polk is still a pretty versatile 3.1.2 setup. It has a better soundstage than the JBL, and it even supports Dolby Atmos content.
