| Thiel Owners Hello all - in response to some questions from some of you who are upgrading your crossovers, I’d like to post some of my reflections. I have uploaded a CAD drawing of my modular outboard crossover cabinet to my virtual system. That drawing is emp... | |
| Thiel Owners @improvedsound - PM sent. | |
| Thiel Owners improvedsound - that's a nice piece of work you have done. You capture the Thiel Essence with the sloped, sculpted contours and the elegance of the base. will post some of what I have learned on this journey through my own experiments and coachin... | |
| Thiel Owners sdl4 - TPC was normally called Electrolytic Tough Pitch (copper), which is motor / magnet wire. The others are more refined in their impurity, crystal and surface parameters. There is a case to be made that ETP is good enough as long as the other ... | |
| Thiel Owners I have learned that the speaker cable in Thiel’s listening room was Kimber Type 88. Let’s grant that Jim, et al, judged that to be his best choice along with his Krell FPB600 and as I remember a Sonic Frontiers preamp. Whatever the gear was, it c... | |
| Thiel Owners roxy - I actually don’t know the name. It was his prototype he brought to CES, possibly around 1980. We used it in our show system and took some flack because the cable cost more than our speakers and power amp combined. Seems like it was a woven ... | |
| Thiel Owners I have some samples of Iconoclast to get into my works. They use similar principles to those Kimber from the 80s (don't remember the name) that were woven, flat, and cost $1K/pair-foot. They were mind blowing. I'm looking forward to the Iconoclast... | |
| Thiel Owners Cables are indeed fascinating, and their interactions with sources and load are beyond my understanding. And a lot of them don't work well with Thiel speakers. For the record - much of my approach to this playback thing holds cost and cost effecti... | |
| Thiel Owners big_greg - I’d like to address your brightness problem. It is odd that the Thiels alone are bright among good company. It seems reasonable to assume a speaker problem. I don’t know the 2.3s, but hear that the original tweeter could be heard as ’st... | |
| Thiel Owners unsound - that self-surround does break down over time. At the time we were trying to minimize the standing wave reflections and non-linearities between the cone and surround as well as ultraviolet deterioration of soft plastics. It worked well wh... | |
| Thiel Owners bobschliff - email Rob Gillum at Coherent Source Service. He knows. | |
| Thiel Owners Yes, of course. That circuitry is already extant in the eq. There is only 6dB of boost at 40Hz vs 12dB @ 20Hz. Tomorrow I'll run today's trials at 40Hz vs straight wire. | |
| Thiel Owners JA - and it is real music from really talented musicians. | |
| Thiel Owners It's not that Jim didn't know about CDs dynamic peaks, it's more like he was trying to cope to keep the equalized bass viable. That woofer was the first driver with his magnetic shorting rings for a more stable magnetic field and it had a huge ove... | |
| Thiel Owners sdl4 - unsound has a good handle on the factors. But there are even more complexities. Jim did a lot of work on that balancing act including the unusually low reactance of his early bass tunings. The phase angles are quite low and at higher impeda... |
