What People Are Saying

Rated 4.3 out of 5 by 15 reviewers.
Rated 4 out of 5 by Sounds nice - problem with UB8200- blocks remote I bought this to enhance the sound of my 55ub8200 -4K (great picture). 10 minute install but when placed in front of the 8200 it blocks the remote signal. I'm going to need to find some way to lift the tv by about 2 inches. Sound is now much better. I guess that the TV sound was missing some good bass April 23, 2015
Rated 5 out of 5 by great for the money for what you pay, this sound bar works great and was easy to set up April 4, 2015
Rated 4 out of 5 by The sound bar sounds better than any for the price It's has great sound and very easy to sat up.The wifi works with any thing you have with wifi.Buy it,you won't be sorry. March 8, 2015
Rated 4 out of 5 by Great Product I had an expensive sound bar for a couple years that suddenly stopped working. (made by another company) I searched for a high quality but affordable replacement and found this one. I listened to it at the store and brought it home. I highly reccommend for value and sound quality. I especially like the easy to use and very intuitive remote control. To be honest, the sound is not quite as great as the expensive previece one that I had for for the money...you cant do better. I am very happy with thi sound bar. February 27, 2015
Rated 5 out of 5 by Sound Bar Audio System with Subwoofer /Blue Tooth I had brought this for my sister for a Christmas gift. I like it so much, I went and brought one for myself. It was so simple to put together. I use it all the time. I keep the volume down on my TV. I like when I turn on my TV, it automatically comes on. February 8, 2015
Rated 5 out of 5 by Awesome product does everything lg says,great product for the price, would definitly buy from lg again January 19, 2015
Rated 3 out of 5 by Works OK but should buy the next model up This sound bar works fine and I have had no problems with it. However, being the low end model, it does not sound much better than the stock speakers on my 42" LG TV. The mids and highs are about the same (modest improvement) and the bass is slightly improved due to the small but still undersized subwoofer. The LG TV and DVD remotes will not control the sound bar, requiring the use of multiple LG remotes, which is a major downside. While I guess I can't really complain for the price (it is pretty cheap after all) you can spend a few more dollars and get a much better LG sound bar. If anything, I'd have to say the speakers on my LG TV are rather good for a smallish flat screen and maybe that's why I can't really appreciate this sound bar. That being said, I have a different sound bar on another TV that cost $70 more that is much (like 10 times) better: room filling sound, crisp highs, clear mids, and heart pounding bass which are absent in this model. Nothing against LG, but I'd recommend buying the next model up. You wouldn't be spending much more and you'd be getting a much better sounding product. December 30, 2014
Rated 5 out of 5 by Great Product Recently got an LG tv and decided to go get a sound bar. Got in the store saw the LG sound bar with woofer.. instantly fall for it. Glad I did, hooking it up was just as simple as taking out the box and using that optical cord to hook to the tv. Sound is great glad I made this choice. December 18, 2014

connecting the bass speaker to the sound bar

what sort of connection is required to connect the bass speaker with the sound bar? does it use speaker wire? i keep seeing red and black connectors on the back of the bar, but nothing is ever mentioned about the base speaker. also, if it does require speaker wire, is the wire included with purchase of speakers like the optical cable is?

or does the bass speaker run off of wireless technology, and doesnt require any wires/cables at all to connect other than a power cord?

Answer: 
You have to use the wires that came in the box to hook it to the sound bar. No, it don't not work wireless. The sound bar system can work via bluetooth but the wires need to be connect to send sound to the woofer.

Answer: 
No, this particular sound bar must be used with its own remote. Turn your TV volume to the lowest setting on your TV remote, then use the sound bar only to control volume

sound bar

Does the sound bar connect directly to your LG plasma TV? Or does it need to connect to a DVD player for sound?

Look in the back of yout TV. If there is an 'OPTICAL OUT AUDIO' jack (square with a hinged door) the sound will come out from the TV directly to your SOUND BAR.
