Rated 2 out of 5 by from Avoid product The Blu Ray player kept cycling ever time I attempted to load a disc. Now it refused to load any disc, cannot find another player that is compatible with the special speaker plugs. Headed for the junk pile.

Rated 5 out of 5 by from Good quality home theater system for the price This is my second LG Home Theater system. Sound is very good for price. I have it connected to my LG OLED 9300 Smart TV. Only one concern is Smart remote control from TV cannot control most futures on Home Theater except sound and power.

Rated 5 out of 5 by from software upgrade I love everything about this system, just wondering if there is an update for the center channel? even though I've made the adjustements, speaker levels, etc., just wish this system had a center focus feature that would intensify the center channel especially during conversations when watching a movie. other than that i'm overly impressed with everything this system has to offer. and to add, i'm losing my roommates bcuz the say its too loud!!!:)

Rated 1 out of 5 by from 4 mo of service It looks great but when you are watching a dvd the system CONSTANTLY FREEZES, I sending it back to LG to be fixed. I will say that I'm very Disappointed in the quality of this product. I have bought over 15 LG TVS & they are all still in service. Never had a any problems with a TV but this Home Theater its very Frustrating to have to un-plug it & wait for it to re-boot.

Additional Wireless Speakers

I have purchased this product and would like to add additional wireless speakers for audio use can they be added to the existing system?
Asked by: ksr2121
This would depend on the additional speaker system you have purchased. As a rule, I would say no. However, there are certain systems that may be available of which I am unaware.

Are all of the speakers completely wireless

Asked by: g12345
No, actually the wireless speakers are not even wireless as they connect to a seperate unit that plugs into a wall outlet. This unit receives the audio signals from the main unit.

TV set up without surround sound

How can I hook up my tv without going through my surround sound. Now I have it hooked like the diagram shows but you have to turn you surround sound on to hear the tv. Is there any way I can hook it up with out having to turn on the surround sound. I bought this system on Saturday Jan.4, 2014
Asked by: dockmaster49
This would depend upon the type of television you have. For example, on a Samsung TV you can choose in its' setup page to run sound thru the TV speakers while watching TV and thru the system when watching movies. You also have the option of running the TV by itself without turning on the LG system. This should (in theory) play sound through your TV speakers.

Is the blu ray drive required?

Do I have to use the blu-ray drive for this to operate properly? I really don't want it but I like speaker system. Also I have 4 gaming systems hooked up to my TV already, I don't have room for another device.
Asked by: Kevin949
The Blu-Ray drive is the head unit for the speakers, it is what powers the speakers. You can connect (up to) two of your gaming systems (or anything else running HDMI) to the receiver. The receiver then has an HDMI out port to connect to the TV.
