Rated 1 out of 5 by from Save your money! After only 17 months, the LG 300 w Soundbar (NB3530A) will not activate (the red light is on indicating it is powered) when the TV (LG 42 inch) is turned on. I have disconnected and reconnected everything to no avail. I checked the TV setup and it has not changed from when the Soundbar was working. It is connected with an optical connector. I am disappointed that it has died after only 17 months. If I have to replace it, I am not inclined to buy another LG product.

Rated 5 out of 5 by from Great Sound Quality The sound quality of this set-up is better than I expected. It is difficult to gauge the quality in store, but what I was able to hear at the store convinced me. When I brought it home and set it up I was blown away. It sounded like I had an expensive surround sound setup. The wireless sub was an added bonus (only needs to be plugged into the wall). I don't notice any sound loss with anything that I use this for. Playing video games with this is awesome as well. This also has Bluetooth which makes listening to the iPod or any other music player awesome. There are different types of sound features you can choose from also. If you are in the market to buy a soundbar, but don't want to spend a lot of money, but still get quality sound then this is the unit for you.

Rated 1 out of 5 by from meh sound quality is decent. at least until you play a game with a lot of noise like engine noise in forza... then its starts too buzz and rattle. the remote refuses too control my LG TV. and the TV remote wont control the bar. oh, and the sub-woofer started to make a repeating BOOF noise for a few min before i finally figured out what the noise was coming from, and realized it was smoking out the hole in the front like a Cheech and Chong re-run... so no thanks, wont be buying it again.

The green lite on the subwoofer keeps blinking green , the sub isn't working 

Asked by: Detroit
When the connection failed, you can see the red LED on the subwoofer and cannot get sound from the subwoofer. To solve this problem, try the following steps. 1. Press and hold STOP on the unit and MUTE on the remote control simultaneously. - “REMATE” appears on the display window. 2. Press PAIRING on back of the woofer. - The Green LED will flicker. 3. Turn off and on the unit. - If you see the green LED, it is successful. 4. If you don’t see the green LED, try again Step 1 - Step 3.
