Our Verdict
Polk Audio Signa S2
Polk Audio Magnifi Max AX SR
The Polk Audio Magnifi Max AX SR is better than the Polk Audio Signa S2. The S2 is a 2.1 setup that's designed for stereo content like most music and TV shows. It lacks discrete satellites and Atmos support, unlike the AX SR. If you want a simpler bar, though, the S2 may still be an okay choice.
