What people are saying

Rated 3 out of 5 by from I got this for free so can't complain but... So , the store it was in had to throw it out and instead I got it off them . Can't complain much for that there but if I anyways opened it up and turned down the subwoofer , all the excess bass was gone. I listen to metal mostly so bass isn't the most important thing there. After calibrating it to metal , it was awesome , great replacement for a tiny 20W system or so but for the price , you can get better options . However , if you do open it hold back the current going to the woofers and increase a bit tinniness by overpowering the resistance , it becomes an audiophile product .

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.

Mine didn't come with a remote, is that a necessity to use Bluetooth? What's the function button do? 

Asked by: PigeonMomma
You do not need the remote if you want to get up and look at the back of the device it should have an (F)press that till the light in the front flashed orange and then when ever you turn it of it will remember that so when you turn it back on it will still be in bluetooth mode

Can the LG soundplate lap340 connect to the Music flow H5 wireless speaker 

Asked by: Muddypants84
The LG 120W 4.1ch SoundPlate™ with Subwoofer and Bluetooth Connectivity, Model # LAP340 is not a Music Flow device and does not have internet connectivity and the LG Music Flow H5 Wireless Speaker, Model # NP8540 is a Music Flow device that can be connected to your home network its built-in Wi-Fi. Even though both units support Bluetooth, they do not transmit Bluetooth, they are Bluetooth receivers so there is no way to connect one to the other...^IFV

After a device is paired through bluetooth, how do you re-enter pairing mode to pair a new device? The soundplate is just waiting for me to repair the old device and will not show up as an available device.

Asked by: Pagn93
We do apologize about the ongoing issue you are having with the unit. To better address your concerns more information would be needed. Is there already a device connected and we are trying to pair a 2nd? Are we attempting to pair another device after the 1st has been disconnected? Please contact LG at 800-243-0000 for assistance with resolving this matter.

Is there a smartphone app that will allow you to control this device

Asked by: Jerry75148
Depending on whether you have an Android Phone or iOS phone, you can look for the LG Bluetooth Remote App which automatically searches for the remote control applications available when connecting to a device that you can use to control the LG 120W 4.1ch SoundPlate™ with Subwoofer and Bluetooth Connectivity, Model # LAP340. You will find the app in either the Google Play Store or in the iTunes Store...^IFV

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.
