Harmon Kardon 5187-2105 full speaker system. Uses 3.5 mm aux to connect to devices and powers with 12 v power supply and will need 2 power supply’s to power the satellite speakers and the subwoofer separately. Condition is good and working with some scratches snd marks on back of subwoofer. Great deal for the full set when speakers alone are found on eBay but the subwoofer is a rare find alone or with speakers. 2 power supplies included in the purchase. Both the subwoofer and speakers can be powered off one power supply when using a Y splitter (1 to 2) to split the power supply cable to 2 ends for one to subwoofer and the other to speakers. This was tested with my personal splitter and message me for suggestions on getting one.
