• LG QNED Matching
  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.
• Crest Design
  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 time² while using one remote to adjust the settings interchangeably.
• WOW Interface
  Now, convenience is in your hand. Control your soundbar and your LG TV with one remote³. Adjust the volume and audio settings, check the connection status and even select a sound mode on the screen, all from the TV remote.
• True wireless connectivity
  Now there’s a surround sound system for rooms of all shapes and sizes. Our new up-firing rear speakers have true wireless connectivity—that means no special receiver needed. Not only do they deliver an immersive audio experience, they can be positioned anywhere and calibrated accordingly. These speakers only need to connect to an outlet—it’s literally plug and play.
• Dolby Atmos with Center Up-Firing Speaker
  Take your home entertainment to a new level with 3 channels and a subwoofer that projects attention-grabbing audio power. The up-firing center channel lets you hear voices with superb clarity and still enjoy the thrilling sound effects. And with Dolby Atmos⁴ and DTS:X⁵ technologies, you will experience a unique spatial sound that fills even the largest rooms.
