Hi Kathy! The subwoofer features a wireless connection to the soundbar, but requires power to operate. For optimal sound performance the subwoofer should remain powered on and connected to the soundbar. If you would like an option that does not require a subwoofer, check out the S series soundbars from Samsung like the S60T at the following link: https://www.bestbuy.com/site/samsung-hw-s60t-4-0ch-all-in-one-soundbar-with-alexa-built-in-2020-black/6400705.p?skuId=6400705 ^Tim
