SJ7 Flex Setup Soundbar w Wireless sub

Introducing a New Way to Enjoy Sound

The LG SJ7 Sound Bar Flex offers one of the most versatile TV sound solutions out there. As different rooms have different needs, the dual-speaker design allows for multiple configurations. This sound bar system consists of two speakers that can be used as one traditional sound bar, or separated into two stereo front speakers, or into a front and rear stereo speaker set up. Or, use one speaker as the soundbar and then switch over to portable mode and take the speaker with you. So now you've got a portable wireless speaker (with built-in rechargeable li-on batter) with a battery life of up to four hours.

For maximum enjoyment of various types of programming (movies, sports, games, etc.), LG-exclusive Adaptive Sound Control can automatically detect what’s playing and then enhance the clarity and impact of the audio.
