Our Verdict

Polk Audio MagniFi MAX SR

Polk Audio Signa S4

Depending on your listening habits, you may prefer either the Polk Audio MagniFi MAX SR or the Polk Audio Signa S4. The MAX SR is a 5.1 setup that comes with dedicated satellites, and it has a better surround sound performance. However, it doesn't support Dolby Atmos content like the Signa S4. Also, the MAX SR reproduces a lot of compression and distortion, especially in the bass range, that affects the sound of your audio.
