If your TV is newer and has an integrated digital TV tuner, you will need an 'optic fiber' cable to go to your speaker system...the system will need to take an optic fiber connection though...most of those little systems don't, in which case you can get an 'optic-coaxial' converter and adapt to the coaxial input on your speaker system. More information, such as model numbers is needed to really be of much help.
