Our Verdict

LG SK9Y

LG SN9YG

The LG SN9YG is a better overall 5.1.2 soundbar than the LG SK9Y. The SN9YG feels better built, it's able to produce more bass, and it can louder. It has a slightly better center channel and surround performance, and there are also significantly more sound enhancement features. The SN9YG has eARC support as well as DTS:X support over its Full HDMI In port. However, the SK9Y has a significantly better height performance.
