This is a 6” 100 watt slim cabinet powered subwoofer that uses a link module to connect to the rest of your home theatre. (Module not included).
Powers on when plugged in, but no way to test the subwoofer since I don’t have the link module.
Perfect if you have a similar Sony (or other compatible) system, or want to turn it into a passive subwoofer via modification.
Note - no input connections in back. See photos. Also visit https://www.sony.com/electronics/support/res/manuals/4529/45298412M.pdf
