Perfectly matches LG QNED series TV

While a great sound enhancer for any LG TV, this slim and compact soundbar is especially ideal for your LG QNED. With its smaller width and depth, the soundbar nests perfectly beneath a QNED on a TV stand. If wall mounted is your style, the soundbar is also fully compatible with the LG QNED Synergy Bracket¹, an easy-to-install soundbar shelf that attaches directly to the TV and not your wall.

Make home entertainment stylish

This is a soundbar that’s meant to be seen as well as heard. It features LG’s new crest design that gives the soundbar a sleek and stylish look. But looks are just the beginning. The metal grill also helps keep dust and debris out of your soundbar for worry-free audio enjoyment.

WOW Orchestra

Create the perfect harmony using the audio from the LG TV and LG Soundbar to produce the ultimate listening experience. Feel every detail of sound. Use the LG TV and LG Soundbar speakers at the same time while using one remote to adjust the settings interchangeably.⁴
