Hi! The Q900TS features new technology we call Object Tracking Sound. Utilizing speakers on all four sides of the TV, your sound will intelligently follow the objects on screen to give you a more realistic sound experience. While it is impressive, for a true surround sound experience we recommend pairing the TV with a 2020 Samsung Q series soundbar. This will allow you to take advantage of Q Symphony, meaning your TV speakers will work in partner with your soundbar to give you our most immersive audio experience yet.
