Those decent enough for free...!
And that "Upper-Mids have one partial pushed in dust cap" issue needs to be resolved. That is the actual dome diaphragm, and not a dust cap. Try to pop it back out, if you feel comfortable enough to try? A paper towel cardboard tube works, if placed over the dome, to "suck it out". A low powered vacuum can work too. Just be careful, as it's not hard to pull the dome from the voice coil gap. Even warming the dome, before and after, with a blow dryer, can help reshape it back to stock. It's actually more cosmetic, as the dome will probably sound fine as-is. Only dispersion might suffer?
A good save, and I hope you enjoy the speakers and equipment!
