Thiel Customer Service - New ownership is terrible!!! - WHAT HAPPENED TO THIS COMPANY ?

I've heard the CS7.2 and 3.7 but a few years apart, different rooms, systems . . . Both are excellent, no doubt. The coax driver in the 3,7 is probably better than that in the 7.2. Makes sense given that it is a later model and would include more of Jim Thiel's advances. The increased rigidity with in the midrange diaphragm likely increases the range of pistonic behavior. The 7.2 almost certainly is better in the bass, going lower and probably also tighter.

Where are ya - aolchris?

Happy Listening!

bettlemania thank you for the input! I could get a rough picture on their comparison. By the way, I remembered some sentence mentioned about the brightness of 3.7. I don't know if 3.7 needs more attention to be matched up with front end.

Perceived brightness with the 3.7s (and other Thiel models) probably says more about the partnering equipment than the speakers. They are high-resolution, low distortion designs. The CS3.7 coax, in particular, has break-up modes well out of the operational range. The pistonic behavior will reproduce the signal with excellent fidelity. Flaws in upstream components are revealed but many listeners just assume the problem is the speakers! Most Thiel models are well-known for demanding powerful amplifiers but please make sure to also use high quality!

The 3.7 is not bright.  If somebody finds it bright it's because they have bright electronics, a bright room and/or prefer a rolled off sound.  They are actually very similar in balance to the 2 2s.
