Our Verdict

LG S80QY

LG SC9S

The LG S80QY and the LG SC9S are both 3.1.3 setups, but the SC9S is the newer model. It offers better overall performance and more balanced sound, especially in the treble. Its unique mounting bracket is designed to attach the bar to a compatible LG TV, which you may also find useful if you own an LG TV. Plus, it has a better stereo soundstage.
