What People Are Saying

Rated 5 out of 5 by from Awesome Sound My LG soundbar really provides the optimal "movie theater" at home sound experience. The unboxing and set up was super simple as I was intuitively guided by the LG wizards technology.

Rated 1 out of 5 by from System is horrible Just bought a 65 inch C9 OLED and wanted better sound... this product is not it. It sounds horrible - plastic and tinny sounding. Further the installation instructions are poor at best - felt like I was playing a game of Pictionairy - nothing but hieroglyphics to try to decipher. Once connected there was no directions to help me understand how to tune the system - can't control the bass, treble, center channel... just clicking buttons randomly with nothing working correctly... overall booo - will be returning product to Best Buy.

Rated 5 out of 5 by from Great Sound I own several large LG products from large to small, I really can't say enough good things about LG. Naturally when it came time to upgrade my sound bar, it was a no brainier on which brand to go with. I'm loving my LG SL8YG sound bar, it has a lot of amazing features like bluetooth, built in Google Assistant and you can really hear the high quality sound and pairs great with LG 75" Nano Cell ultra-premium LED TV for the ultimate entertainment experience.

Can the subwoofer be laid flat (on a wood floor) and placed under the couch? If so, would there be any degradation to the sound quality?

Asked by: Melchizedek
Subwoofers are omnidirectional so in most cases, their placement in a room is not an issue unless you have furniture or other objects that are blocking them and the acoustical properties of your room may also affect them. Placing a Subwoofer under a couch is an unconventional placement for a Subwoofer and not something that is tested for so there is no way to predict how the sound would be affected...^IFV
