Blown Thiel 3.6 tweeters/midrange

The Aragon is in perfect working condition so the problem is defintely not with the amp.

i'd check your amp. sounds like it shorted.

I owned the 3.6's for a few years and had to replace probably 5 tweeters and 3 or 4 midranges. I was using a krell ksa 250 amp at the time. I don't think this speaker is meant to produce very loud music as my wallet will tell you as I never learned my lesson with regards to volume. I had one incident like your friend when both tweeters / mid's failed. I had always sent the failed drivers in when I got replacements but never received any feedback as to the root cause of failure. In the case of the four drivers going out I actually had damaged / failed crossover.Luckily I live about 70 miles north of their factory so I drove the speakers down to them to repair. To Thiel's credit they fixed all that was apparently wrong and after doing a frequency response test discovered a problem with the other speakers crossover which they pulled and fixed. They also gave me a very thorough plant tour and was treated to their custom build listening room which housed about every statement component from all the " major manufactures ".

I suggest that you send a quick e-mail to Thiel (mail@thielaudio.com). What you describe sounds a bit odd (both?!?) but Thiel has been exceptionally helpful in the past. (One of the rubber skirts on a bass radiator on my 2.3's came unglued, I gave Sherri a call down at Thiel (Telephone: 859-254-9427 | Fax: 859-254-0075) and she admitted that she'd never heard of that happening before and sent me a new one without even having to ask). Like most higth-end shops, they take great pride in making sure their equipemnt works and will help make sure that it does. A great resource, not to be overlooked.
