Great sound system
This system is one of the best. Love the quality and the sound that produces plus the bass sound is unique. The speech part is a bit low at some parts when you are watching a movie but overall it is one of the best sound bars out there.

Very cool, sounds terrific, really easy to set up
I've had it about a month and paired it with an LG TV and setup was a breeze, controlling it with the magic remote from the TV is super easy and it sounds good. I also have the google assistant working and have cast music from my phone to it - it is essentially the new home speaker system

Amazing Sound Bar!!
I enjoy using the sound bar for watching movies, because I really like the home theater aspect of loud surround sounds while I'm more engaged into my movie. The sound quality is excellent from the sound bar and the subwoofer is just jaw dropping of excitement by the feeling of the bass vibration traveling across the floor.

Issues with Soundbar
I bought this sound bar about a year ago at the same time I bought my 75" LG television. I had the Geek Squad from Best Buy install everything for me. It worked beautiful until a couple of months ago when all of a sudden, the sound stopped one day. The Geek Squad returned and asked me where the remote control was for the sound bar. I never got one. So they adjusted some settings, and it worked - for awhile, but periodically, the sound just stops, and I have to plug, unplug, and replug the sound bar power cord back in which seems to help. I am still trying to find the remote that goes with this product, and no one is able to help me.

Had to send it back for repairs
Wasn’t impressed with the sound and thought it could be the setting in my tv causing the sub to cut out or even wireless interference. After paying more attention to the actions of the sub it got to the point where it was all the way up and sounded like the speaker was no good or possibly the internal amp or power supply wasn’t able to power the sub. Ended up getting to the point of shipping it back to LG’s service center and I’m waiting to hear back on what they’re going to do.

Attention Grabbing Appearance and Sound
Sound bar is wonderful when the e-Arc works! Although I bought it open box the store assured me it was in excellent condition. The sound bar is paired we a LG8570 UHD television. Often times when switching channels or watching a program the sound bar loses its sound completely. I have to go through the functions to return the sound or power off, which is very frustrating having to use multiply controls to restore sound to a highly expensive product.

Dolby Atmos must!
Paired this system with the SPK8 rear speakers and this system is awesome. make sure to download the soundbar app and leave DRC off. This way the sound is much fuller in the rear
