I had a pair of XPL200's and I loved them, clear and very fast transients. I would suggest that you keep looking for a replacement 046ti tweeter on ebay as they DO come up once in a while. The XPL140 uses the same 046ti tweeter I believe.
There's a single JBL 046Ti-S1 tweeter on ebay now, check it out!
I sold my pair because I damaged one of the 3" titanium dome midranges. Those are also very rare, but CAN be found. The 3" midranges are either model 093 or 095 but can be replaced with a modified T030 from their car speaker line by removing the internal crossover. I'm pretty sure this can be done with the tweeters from the car line as well. I will post again after doing more research. Good luck.
