Our Verdict
LG SP9YA
Samsung HW-Q990B
The Samsung HW-Q990B is better than the LG SP9YA. The Samsung comes with rear speakers, meaning its surround sound performance is more clear and real. Its Atmos performance is better, so sound effects reproduce more accurately in the mix. There's even a graphic EQ on hand, which makes it more customizable than the LG. However, if you don't have room for rear speakers in your room, the LG is still a versatile alternative.
