What People Are Saying

Rated 5 out of 5 by from Awesome Product. I've never seen this product before from where i'm from. I believe it never entered the Canadian market. Regardless I found a Canadian website selling the LG LAP340 soundplate. I love the fact this soundplate has only 3.4 CM height and that it can fit under the TV. The sound quality is great, but i find the cinema mode overly done in some occasions. The 2 subwoofers inside this system are adequate. I would recommend this product to anyone looking for a ultra thin sound solution.

Rated 5 out of 5 by from Good sound, enjoyable features. Easy to setup. Great sound. Would be better, if it came with the controller, but it was missing.

Rated 4 out of 5 by from Overall a great item I am a bit disappointed that you can't adjust the audio on this unit. The bass can almost be a bit much sometimes. I also think it would sound better if the unit had more space between the bottom and the tv stand. I think sound gets trapped since the speakers are underneath with little room to expand. Easy set up, great looking

Rated 2 out of 5 by from It's all about the bass ... and only the bass. The bass response is incredible. If that's the only audio signal present, but music with treble sounds horribly washed out, compared to speakers which have a more complete audio range.

Rated 4 out of 5 by from Great sound but interface needs improvement I got this a couple of months ago at a local store, I think it improves the sound of movies and TV shows, however the interface needs a little improvement: - It should turn on automatically when receiving optical signal. - One LED to show current status? come on, I need more information without having to press the remote's buttons to figure out it's current status, I need more display information: - Current volume level. - Is Cinema sound on/off. - Current Input mode (Optical / Bluetooth).

Seasons greeting! I just purchased this unit and was wondering how I can reduce the bass? My LG TV can adjust the sound effects when connected to Sound Sync.  It's seems to be a great unit and just what I need, but the bass is just to powerful.

Asked by: James815
We regret your dissatisfaction with the operations of this Sound Plate. Unfortunately, there does not appear to be an option available for modifying the BASS output of the speaker system. This may be adjusted, to some degree, through the audio settings on the television. It is not possible on this device.

Purchased used open box unit without remote. Please provide remote control codes

Asked by: Mannnnnix
All codes to be used for programming the Universal remote control will be located in the setup instructions for the Controller. If you have experienced trouble in locating codes for LG, you may also try using Zenith or Goldstar codes, as some of these coincide with LG frequencies. If these do not resolve the matter, then the two devices may not be compatible.
