I’ll take the opposing position and recommend passing on these. The photo you provide indicates they need work. Potentially alot of work and not just on the drivers, but likely the crossovers as well.
You will need to spend a considerable amount of time and a not so insignificant amount of money before you can even determine what they sound like and whether you like that sound. Additionally, you will need to buy some electronics and interconnects and a source. I’m not even sure I would consider them at half the price or free. There are some pretty satisfying speakers available today that would likely be a much better investment. Additionally, since you have no other gear driving the decision, there are some nice speakers available today with built in amplification (Kanto Tuk, Vanatoo, even Kef LS50W) that you could conceivably drive with a personal computer, your television, via wifi or your iphone which would likely be a better investment for you than these.
