| Thiel Owners Prof, I had seen that quote from Phil here before. The story from Thiel doesn't really match all that well. Regarding the 2dB/decade, I don't really see that in my perusal of comparative test results. I wish that Stereophile had reviewed the 2.7 s... | |
| Thiel Owners Jeff, the point is that such a system (CSnext) required far more horsepower than available from an individual who may have played some minor role. Creating a design team after Jim's departure was a huge undertaking. The 2.7, 1.7 and MCS (#next) we... | |
| Thiel Owners For the record regarding product development. Jim was a sole developer with support from Gary, Rob, Kathy, etc. The 3.7 was his last product. The 2.7 was a spin-off, as the 2 series had always been. It took $6 figures to develop that product with ... | |
| Thiel Owners Regarding CS3.7 iterations. I remember someone here getting 3.7 revision 2 crossovers from Rob. Can you tell us anything about the qualities of the revision? Thanks for any input you can offer. | |
| Thiel Owners Excuse me, that's 2.6 ohms.TT | |
| Thiel Owners Ron, I don't have enough history to comment on your situation. I am far away and out of touch and coalescing probabilities from sketchy evidence. The detailed lab records are MIA and most of what we know is in Rob's memory. I am gradually back-e... | |
| Thiel Owners Ron, I see from the XO schematics that the higher input sensitivity of the 3.7 is due solely to its more efficient woofer. The 2.7 coax has resistors to pad it down to a less efficient 8" woofer with the same coax. No satisfying answers yet. | |
| Thiel Owners I'll try to find out something from Rob about the 2.7 vs 3.7 failures. Same driver.Thieliste, good investigation. In the day Thiel, especially the CS5, was very successful in Japan. Luxman amps were the clear choice in ultra high-end systems. They... | |
| Thiel Owners Ron, your listening levels and amplification are very appropriate / safe. So something else is going on, perhaps bad drivers, but sometimes cables can induce amp misbehavior that adds stealth distortion. I can't troubleshoot, but I will try to fin... | |
| Thiel Owners Ron, all of your failures sound like overheated voice coils, either delaminating or in the case of humming along, being loose enough to squirm on the former. The cause is most probably being fed a distorted / semi-clipped signal. The first driver ... | |
| Thiel Owners Ron and all. I placed a query to Rob via phone message this morning. I will post what I learn. This information is indeed germane to all on this board. | |
| Thiel Owners Ron, shorter cables are always better than long. But parallel (not twisted) conductors like Goertz are inherently capacitive. If there is a problem depends on the amp. But Thiel's low-impedance results in more current being drawn through the cable... | |
| Thiel Owners The Goertz design is high-capacitance, which may cause some amplifiers distress in the trans-audio high frequencies, which produces down-reflected audible consequences. Correcting that capacitive load makes the amp run truer to form. | |
| Thiel Owners The most common oddity from a woofer is the bottoming of the suspension: the spider hits the basket plate. Thiel's short coil is out of harm's way from bottoming on the back plate. The voice coil adhesive is high-temperature. So, unless you overhe... | |
| Thiel Owners I like spade connectors. |
