Tweeter Replacement for Acoustic Energy (UK made) - AE2's and AE5's


I have a pair of each AE2's and AE5's - circa 1997.  Both had SEAS - The AE5's Original was 25 TAFCD/W AE - H 849 8ohm The AE2's had 25TACF/W-AE which AE said a few years ago to use the 27TBFC/G - H1212-06 - which I did replace in the AE2's, acquiring from Madisound here in the USA, yet had an issue with one so I want to replace both again, plus the AE5's.
My recent communication with AE, they are stating they can now provide all replacements, yet pricing is high, plus they said the AE2 tweeters would need a component change to the crossover, which they would supply.  AE is not providing specific info on the replacements as they want me to go through them, moreover there Replacement cost's quoted are very expensive, furthermore the crossover component change with the AE2's complicated the situation even more.

Originally, a few years ago I was looking to upgrade all Tweeter's, even with a different manufacture other than SEAS if necessary, yet continued to be told the H1212-06 was the best solution.

Now with the higher pricing from AE Direct, I have been extensively researching options to no avail due to all the variables to properly match and maintain, if not improve the total high-end performance these speakers provide.
Any comments, sources or suggestions would be Greatly Appreciated. I Thank You in Advance.

I have the same problem with blown original AE tweeter, looking for replacement.  
AE Makes many speakers, it is Critical for me to know Exact Speakers you are referring to.. as in the Model and possibly the year or how old they are?
AE2 Signature or regular? The crossovers are different, which influences the tweeter, and why I asked..  I Probably have 30hours minimum in Trying to make mine as exact to Factory as possible, including All OEM Sources, part numbers, dealing direct -  many emails with AE north of London proper.. Blah, blah..  I'm in Atlanta, GA USA, where are you?  If is is Important to you to have Corrected to Spec, then maybe we should talk or email off line to our other emails since I don't hang out on this forum and we would need to share pics or at least you need to pull your tweeter and take pics and send me front and back.   All their tweets have been superseded with Other..  and Original OEM Supplier for those years (mine are same, bought in 1997 and LOVE THEM!). back to OEM it was SEAS out of Norway and I even delt with them directly too.    Up to you on how you want to proceed, yet it is Not a Simple Go Get This One!  ESPECIALLY if You Want to Keep the AE Original Quality Soundstage wise, which was 100% Critical to me to do,
