The LG DSC9S soundbar is primarily designed for operation with the wireless subwoofer to achieve the full sound potential. However, it is technically possible to operate the soundbar without the subwoofer.

If you use the soundbar without the subwoofer, most of the functions will still work, including the upfiring speakers and the AI sound processors. However, the "Wow Orchestra" feature, which is part of the comprehensive sound system, will not be fully utilised as it relies on the synergy between the soundbar's speakers and the subwoofer. Without the subwoofer, you will not fully experience the deep bass and spatial sound distribution that the "Wow Orchestra" offers.
