LG sound bars can fill a room with exciting, immersive virtual surround audio. Selected models can be upgraded to true surround sound with additional rear channel speakers (sound bar sold separately). The contents of this set can transform a living room into a home theater. This easy-to-set-up rear channel speaker kit is designed to create a wireless connection with the sound bar and enhance surround sound performance. For even more design flexibility, these speakers can also be discreetly mounted on the wall, which is especially convenient when there is no table or shelf nearby.
