| Thiel Owners Pass' Threshold amps do quite a bit right for all the right reasons. | |
| Thiel Owners JA - I hardly ever get back to Lexington, but that will change with the Renaissance Project. I'll look him up! | |
| Thiel Owners Utrak - your room is small, but its proportions are very good, plus you get bass room gain without supporting the deepest and most problematic frequencies. Yes, they are quite efficient and the impedance doesn't drop as low as newer models, plus t... | |
| Thiel Owners Utrak - I can offer a broad-brush intention: more than a dream, less than a plan. Rob of Coherent Source Service and I are working on upgrades for various classic Thiel models. The CS3.5 is now on the list, and the CS3 is likely to come along as a... | |
| Thiel Owners I think it not improper to point out that JA seems to hear what his measurements tell him. At 50" there is a midrange suck-out and some spikes. Notice that he wonders in print if that is what he is hearing. However, those ARE measurement artifacts... | |
| Thiel Owners I interpreted "all pass" as any filter that is not causing a rolloff. As I used the term, there are multiple all pass elements in all of Jim's crossovers. They include various shaping and resonant circuits which are directly opposed to specific re... | |
| Thiel Owners Beetle - I am substituting caps in the PPs and 1.6s, which directly track your experience. | |
| Thiel Owners That photo is probably an early or prototype version which goes to shows and seminars. Typically it will morph through a year or more to match the actual settled particulars of its driver complement. At first glance, coils are 4-9s, best of form. ... | |
| Thiel Owners Andy - that's a CS6 XO alright. What a beast! I sent you a PM.TT | |
| Thiel Owners Andy - I haven't seen the CS6 XO, but can comment generally. Jim employed all pass filters - Zobels and custom - to counter rising impedance with rising frequency as well as shaping networks to trim each driver toward its theoretical optimum respo... | |
| Thiel Owners Cat - for the record, I agree that a subwoofer solves many problems. And for the record, Jim also agreed, but we weren't ready to address subwoofers at that time in our development and, especially then, subwoofers were routinely badly implemented.... | |
| Thiel Owners Prof - the 02s have not yet arrived due to complications at their Virginia storage location. Should be here soon. A proper resurrection must include new drivers, since the originals are no longer made. I am exploring. I'll stay with fiber diaphrag... | |
| Thiel Owners Guys - I am approaching the 02 first for lots of reasons including access to alpha-testing a new port technology in addition to the MO being developed for the other products. Can this forum provide an idea of how many pairs are out there? How many... | |
| Thiel Owners The 3.5 EQ will stay, since it is a vital part of that product. The sealed bass drops off about 100 Hz at 12dB / octave. That would blend very well with a subwoofer, but by itself is pretty bass-shy. The two position EQ extends to 40Hz and 20Hz, w... | |
| Thiel Owners Dino - you may know that I had axed the 3.5 from my original short list upgrade program because of driver availability problems. However, through this thread and other investigations, I sense that the 3.5, along with the 2.4 are the strongest cand... |
