Our Verdict
Polk Audio MagniFi MAX SR
LG SP9YA
The LG SP9YA is better than the Polk Audio MagniFi MAX SR. The LG is a better built 5.1.2 setup that supports Dolby Atmos content. It also has a better soundstage performance, and more sound enhancement features like room correction. That said, only the Polk Audio comes with discrete satellites included.
