Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Full Room Sound

LindaMtShasta 3/4/2021

I bought the LG soundbar three months ago and am completely amazed at the quality of sound that I am hearing. LG bumped up the sound on a very high end tv to excellent. The set up is seamless. Adjustments to the soundbar speakers are extremely easy with the remote and I have done so with different movies for optimal listening. Great addition to entertainment

I have had this sound bar for a month now and it has worked great. We really like the sound it puts out. The look is also perfect as it is flush with the wall.

Sound is OK but remote doesnt work.

Dawg Fan 1/19/2021

I received this sound bar as a Christmas gift. The bass is excellent but a little disappointed in treble - sounds muted compared to my TV speakers. Also the remote doesnt work. I contacted customer service and they are very good. I was quickly sent a new remote which doesnt work either so Im sending the soundbar/subwoofer back for repairs to the IR sensor. LG pays for shipping on warranty repairs.
