Rated 4 out of 5 by from Extra sound I bought a 75" TV and I wanted to "Upgrade" the sound system. I bought a 75" TV and I wanted to "Upgrade" the sound system. I have used and trusted LG for quite some time and they did not disappoint me this time. Easy to set up and with a little fiddling with options I was able to get the performance I was looking for. I purchase both the Sound Bar with wireless subwoofer and the Rear Speaker Kit. They work together quite well and work with the TV seamlessly. The theater-like sound in my home, Lifes Good. db

Rated 5 out of 5 by from Great sound, easy to install Love the product. Came well packaged with clear installation instructions. We were enjoying the great new sound within minutes of discarding our old out of date surround sound with the huge wire mess buried behind our entertainment center. It was also nice that it came with everything needed to get it up and running, instead of having to run back to the store to buy things that were not included for set up and operation.

Rated 1 out of 5 by from Only my right channel works. I just purchased this today. I was so excited to use it. Install went quickly and simply. Hooked it up to my LG 4K. Everything looks nice. Turned it on and . . . . Sound is only coming out of one side. I exhausted every option. Sadly, it is just plain defective. Too bad to.
