Our Verdict

Samsung HW-R550

LG SL6Y

The Samsung HW-R550 is a better soundbar for dialogue and TV shows than the LG SL6Y. The Samsung is better balanced for reproducing vocals, it can get loud enough for normal use, and it has a graphic EQ if you want to tweak its sound a little more. However, the LG has better center and surround performances even though all surround content is still downmixed into stereo. If you connect a device to it using its HDMI input, it can also easily pass a full 4k signal, although it won't pass HDR10 content through.
