Our Verdict

Polk Audio Signa S4

Polk Audio Magnifi Max AX SR

The Polk Audio Magnifi Max AX SR is better than the Polk Audio Signa S4. The Max AX SR is a better-built soundbar with discrete satellites to improve its surround sound. It gets louder, too, and it offers a more extended low-bass. You have more wireless playback options, too.
