The sound bars shouldn't be lacking for audio quality, either: The sound bars lean into LG's previously announced collaboration with high-end brand Meridian, which will contribute sound-enhancing technologies including Bass & Space, Image Elevation and Meridian Upmix for converting stereo content to multi-channel.
