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.

Why would you not trust the manufacturer on what to use with a specific model?  Because they cost more?  There are hundreds of possible options that are wrong and only one that is right, why not go with the sure thing that the company who built the speaker recommends?  If it costs more than it used to, everything costs more that it used to (before pandemic) and I'm sure the entire speaker system would cost much more than it did when new in 1998.
Here is the Answer Finally especially for ettorreit and also for lonemountain.
I went back to all of my records and correspondence on the Tweeters including AE directly. from 2018, yet had even earlier communications with them/others to Match them Perfectly to original spec.  Until 3/2/20 as a follow-up from AE from previous years past, they now have found a supplier source and will sell direct as noted below.
Reply Direct from AE:
AE5 Tweeters £108.33 each
AE2 Tweeters £124.99 each

Each price excludes Tax and shipping. 

The AE2 tweeters would need component changes to the crossover, which we would supply with the tweeters along with instructions on the necessary changes to make.

Prior to that their recommended replacement was:
SEAS Prestige 27TBFC/G (H1212) Aluminum/Magnesium Dome Tweeter.
Which I purchased on 2/6/2019 from Madisound.com in the USA  @ $51.80 each USD plus shipping..

Hope this helps.

Hi. Found this thread and was curious where in the US I can find the drivers for AE2 series 2. Or the refoaming kits. 
 

Thanks.

Thank you Jweilers1. Perhaps I misunderstood. I was talking about the woofers. It seems like you addressed the tweeters in the above posts.
