So I have a pair of speakers a friend who was moving left behind a few years back. I now want to get them up and running, but I don't have much of a clue how to do that. The speakers are two 3ft tall speakers, the only thing on the back of them is one read and one black spring loaded inputs (no power outlets or anything like that). So in order to get these up and running do i just need an AV Receiver and some speaker wire pin connectors? Or is there more to it than that. Any push in the right direction would be much appreciated!
