Our Verdict

LG SK9Y

Samsung HW-Q70R

Even though the LG SK9Y is a 5.1.2 setup and the Samsung HW-Q70R is a 3.1.2 setup, the Samsung is a better-mixed usage bar. It can get louder than the LG and has a noticeably better stereo performance, especially because of the great bass the sub provides. However, the LG has side-firing speakers and the Samsung can’t play surround content due to its configuration. The Atmos performance is also slightly better on the LG.
