Thiel Owners

Hello
I have been a long time reader and fan of this forum. I have Thiel cs7 that have been upgraded to the 7.2 to say that I cheated on the audiophile path would be an under statement. i bought my speakers from a fellow audiogoner appx. 5 years ago, at that time I thought my Krell ksa 100 amp would suffice, but everything I read said 7.2s NEED power and plenty of it. So I started researching and listening to bigger amps. i was just about to pull the trigger on some Mac 501s when I read about the Thiel liquidation auction in Tn. I now have the Krell fpb 600c that Jim used to power his/my speakers.
When I bought the speakers the concrete baffles were cracked but everything sounded great. Now with the bigger krell on the speakers I am getting air through the cracks which causes distortion in the woofer of my left speaker.
I talked to Rob a few years ago about the cracks and he said there was a small shop near Thiel in Ky. that use to do those repairs but they closed about the same time Thiel closed. 
My big question is "has anyone repaired a cracked concrete baffle or know someone that can repair a concrete baffle"?

I just learned something from Rob Gillum regarding 3.7s.He told me that first generation 3.7s coax incorporated a silver bezel, latest generation have a black bezel instead of the silver one.

There is some reference to that issue here - https://forum.audiogon.com/discussions/thiel-owners-2?page=87

Best bet is to look for someone local or directions like - https://www.bobvila.com/articles/how-to-fix-cracks-in-concrete/

I owned Thiel 7.2s many moons ago but mine had the mineral composite baffle.  Don't know if it true or not but a couple of people told me there were a couple of reasons for the switch.  One was about 15 pounds of weight difference per speaker and the other was problems when speakers were shipped overseas (e.g. Asia)

@scubabird, I too think the closest model to the legacy Thiel’s currently made at that price point is the Vandersteen 2’s. On the other hand, the attributes that you singled out; ...”exceptional detail and clarity...”...is where they separate the most. The Magnepans previously mentioned share most similarly in transient response and to some degree in coherence (compared to others), but are quite different in other ways. Based upon your previous post, I think you’d be happiest with genuine legacy Thiel’s.

I read the main reason for the change was the cracking of the baffles. Weight being second.
