The SC9 and SE6’s performance is “boost” by a Triple Sound Optimizer function, while Smart Up-mixer converts stereo music to multi-channel surround sound. LG claims that its AI Room Calibration adapts each soundbar to its environment, boosting low-end frequency range and subdividing the front channels for improved balance, crisper voices, and enhanced conversation. The SC9 and SE6 also offer an AI Sound Pro function that analyses material – movies, games, sports, or music — and applies the ideal settings automatically.
