Dunlavy SC IV A harsh high frequency

I have owned my SC IVA for many years. I replace the blown tweeters at least once a year. I know the original set were carefully matched at the factory but I can not duplicate the tecniques which John used in his shop to optimize response. The speakers sound glassy and I wonder if this is as a result of tweeters I have installed but would have been rejected by John. I have done a lot of work with room treatment,changing source, components, etc...
Are there any recommendations for fixing this issue?
Replace the Vifa tweeters with more expensive ones?
Thanks

Thanks for the responses guys. I am indeed concerned about my hearing. I have done a lot of bird hunting and I fear my right ear may have some damage. I need to have it checked for sure. I also listen to concert videos at 80dBs. My right front speaker blows a tweeter more than once a year. I have loved these speakers for many years but it may be time to let them go. My 9.4 system is made up of:
2 SCIVA s front LR
1 HRCC center
4 SCIII rear and LR surrounds
2 SCIs for front wides LR
