Monitor 50 Tweeter issue

I recently purchased a pair of Monitor 50s from someone used. Long story short, I was told they were fully functioning, bought them without listening to them (mostly because of COVID, I know bad idea), and sounds like the tweeters are blown. The guy gave me some of my money back, so I only paid $20 for them. I checked the jumper plates and made sure they were connecting, and nothing from either one. I pulled the tweeters and checked the wiring, and it was all connected. The last thing I did was remove the jumper bars and just wire to the upper terminals, and still nothing. Is there anything else I should do to test the tweeters? If they are blown (like I suspect), is it worth getting new tweeters to repair them, and if so, where should I get the tweeters?
