Hi,
I'm not sure if I understand what happened. But how can the act of reversing the speaker connection could fried your tweeters?
So your right speaker is fine. Did you try hooking up the left speaker to the right channel of your amp? If your left speaker still not putting out the high than ther is something wrong with the speaker and not the amp. If the speaker is bi-wire able than just connect the speaker cable to the high section only and see if you get anything.
Well, with that many tweeter on your speaker...I don't know how they are hooked up inside. It is possible that one could be out if you still here some high. You could play music with lots of high frequency softly and put your ear close to those tweeters one by one and see if any of them is out.
Hope this help and remember to be careful when connect and disconnet speake wire... especially with SS amp. Better to turn it off first, wait a minute than connect or disconnect those wires.

Take care,
Buddy
