Wireless for tv connection but they need a power cord for turn the unit on.
Sorry, there was a problem. Please try again later.Wireless referred to the fact that the unit does not need to connect directly to the sound bar or other audio connection. It receives the sound wirelessly from the sound bar. This allows you to put the subwoofer almost anywhere within a certain distance away from the sound bar with running cables to it. The plug in the back is a power cord to power the unit.
