Auto Sound Engine

LG Auto Sound Engine optimizes your sound at any volume level and maintains precise frequencies at all times. This provides the appropriate sound balance regardless of the volume.

In simplistic elegance, allow the Sound Bar to perfectly complement its surroundings. Specifically designed to match and enhance your TV.

Bluetooth Stand By

Sound starts the moment you transfer audio to the Sound Bar. The Sound Bar remains in sleep mode but turns on and begins playing when the audio is sent via Bluetooth.

Energy Rating A+
LG 300W 2.1ch Soundbar | SJ3 is rated 4.3 out of 5 by 8.
Rated 5 out of 5 by from Great Sound Improvement Recently purchased this as my existing home cinema 2.1 system packed up after 9 years of faultless service as the TV sound is not acceptable as like all LED screens are these days. Buying this sound bar I was sceptical at first that it did not sound as good as my hcs I replaced, but with using the ASC feature button on the remote I was Wowed! and now it is set up with some innovative idea of mounting the sound bar on mounting blocks I made up from using old discarded polystyrene packaging using some black card and hey presto I now have the sound bar located where I wanted it to be( see images_

Rated 4 out of 5 by from Quality but a little dissapointed it feels like a quality bar. the clarity is very good. But unfortunately those 300 watts are going somewhere else because it's only as loud as my television (the tv hasn't anywhere near 300w dedicated to sound production), which is the reason why i decided to buy a sound bar. The cheap sound bar i have in the teenage spare room rated at 140w is just as loud and the clarity is very acceptable ... i tried multiple ports and tv's to see if it is a factor (usb and standard tv are notibly quieter) i bought two sj3's (one as a gift both same same). I can even compare it to many other little audio systems i have got and made. purchased and diy. i have personally had televisions with significantly better standard sound built in. So all in all it is quality, but it's not an upgrade, more of a standard that t'v speakers should be stock standard. Just my view and exp.
