pops, I love both the ATCs and the Thiels. Both are great products intended to be as accurate as possible but with somewhat different ways of going about it. ATCs are usually active and the company is mainly known for pro audio. ATC has been building its own drivers for a long time and their philosophy is that if you build drivers well enough you don't need a complex crossover. I think Thiel is not that far from that. Thiel produced passive speakers for home audio so they have different strengths. Thiel had complex crossovers for a long time to fix drivers that weren't as good as they could have been. When Thiel came out with their own drivers the complexity of the crossover dropped significantly per Tom Thiel in this thread.
The founders/designers of both companies were piano players. They're both hard science guys. I get the impression that Billy Woodman isn't quite the obsessive perfectionist that Jim Thiel apparently was. Both companies use small diameter midranges which I've found that I prefer. Not sure why, lighter weight leads to faster response or maybe better dispersion.
