| Thiel Owners I like where you are going. It might be possible to move the coil, if there is room in the cabinet. We could move the 0.15mH coil outboard past the end of the panel. That would require crimping and soldering lead extensions - not desirable, but po... | |
| Thiel Owners I do not have a rule of thumb for how to account for changes in ourboard XO environment and I think any changes would be small enough to dismiss in the absence of research equipment and process. 0.01uF is very small for these voltage and current p... | |
| Thiel Owners 7' from the wall is a great luxury. Do you also have a high ceiling? Ceiling bounce is a real issue. XO layout space is a real issue that will have to be engineered as we go. Thiel used good resistors, I don't remember the facts. You might trace t... | |
| Thiel Owners beetle, the actual combined cap value is important for proper tonal balance and phase addition thru the XO region. I like the CSA +, + with the 0.33 being a teflon or other ultra-grade cap if possible. Ultra bypasses are far less important on the ... | |
| Thiel Owners Beetle, I do recommend coming as close as possible to the original value, since that affects frequency balance and phase addition through the crossover. I am a big fan of double-bypassing and like your idea of adding the third cap to hit 27.93uF. ... | |
| Thiel Owners David Fox sent me a photo of the CS3 with dual binding posts. Indeed that speaker, #539, would have been built months into the product life-cycle, and I would have been the person who made the silk-screen and punch jig for that plate . . . Hmmm .... | |
| Thiel Owners unsound - Please note that I am not in a position to actually transform these ideas into reality, although I am dreaming some dreams . . . Regarding multi-amplification, the signal-shaping was done within the amplification envelope, wherever it ma... | |
| Thiel Owners lrsky, Thiel has used air core inductors since the very beginning. And since the development of the 03 in 1978 and going forward, we used six 9s copper in all chokes and internal wiring. At the time we were an innovator with film capacitors and ev... | |
| Thiel Owners I am interested in developing a "felt need" list of priorities for legacy Thiel upgrades. The 3.5 with its EQ might be a candidate, but I need more than a hunch. I can tell you that the equalizer was dear to Jim's heart as a good solution to the p... | |
| Thiel Owners JA, Please contact me at tomthiel@worldpath.net Thanks,Tom | |
| Thiel Owners Nice to see all these Thiel pixels! My (memory of) 38" ear height relates to average seated ears. I don't know what height was assumed after mid 90s, but probably the same. Measurement distance is 3 meters with an assumption of that as minimum lis... | |
| Thiel Owners Prof, my detailed response didn't show up. Hmmm. Bottom line is that the height change from feet is very small compared to the sonic integration triangles at normal listening distances. 38" ear height is design target. Baffle motion from recoil fo... | |
| Thiel Owners In my opinion amplification and all other elements of the chain are very germane. Thiel speakers reveal upstream misbehavior extremely "well". This battle never ends because only by ultra-resolution can we retrieve the inner detail of music. | |
| Thiel Owners An amp with zero loop feedback must be extraordinarily well designed to work for music. Feedback disturbs phase response. Ayre is addressing design from first principles and I would expect all their products to be very clean, especially in the tra... | |
| Thiel Owners Stereophile's measurement design is an example of what I believe to be a fundamental lack of understanding of the ear-brain and its response to whole-goods: that is sound with its tonal, spatial, transient and dynamic characteristics, to name a fe... |
