| Thiel Owners One interesting aspect of external crossovers, is that so many aspects in the cabinet are devoted to vibration management. Gluing the parts to the board impinges on thermal stability, but if left unglued, they rattle and buzz and introduce microph... | |
| Thiel Owners Beetle - problem is I don’t drink coffee. Proper number is -0003 is the reference A. Good catch. How’s the coffee?There are plenty of good reasons for an external XO. But it is tweaky, difficult and would put off many people. In the case of the 2.... | |
| Thiel Owners Thiel is considered by many to be a small signal transducer. It works best on vocal and/or small ensemble work. I agree and chalk that up to broad range requirements for overlapping drivers. OK, fair enough.I have been dreaming in the way-back mac... | |
| Thiel Owners Guys - I would like to provide a report of general status and recent work. As many of you know, I am deeply immersed in redevelopment work. That has led to many rabbit holes, each of those leading to its own warren. The possibilities are limitless... | |
| Thiel Owners Rob - you have stirred the soup. It's still cooking . . . | |
| Thiel Owners Blue - sometimes the least expensive route is to repair yours. | |
| Thiel Owners Indeed carbon rocks. And I salute Richard Vandersteen all around, and his implementation of carbon on a balsa core in particular. Jim used aluminum on a styrene core - a poor man's implementation of the same concept. And going back to the 2.2 woof... | |
| Thiel Owners Good analogy. And in the new-goods retail market through retailers, the raw component costs are multiplied by at least 5. So every penny counts. You guys as end users are in a different paradigm.Erik - what is your target frequency response, eithe... | |
| Thiel Owners Masi - Rob does do the ferrofluid 3.6 tweeter. Rob has rebuild kits. That tweeter was entirely custom and not replaceable. | |
| Thiel Owners I think a little shot of history might be in order. Let’s look at resistors for a glimpse into Jim Thiel’s working ethos. Of huge importance to Jim was that of balanced design. He worked toward a performance plateau where all elements worked equal... | |
| Thiel Owners Rob and Erik - The 400uF electrolytic is in series feed to the midrange. Bummer. | |
| Thiel Owners Rob - caps always improve via parallel smaller values. Jim never went over 100uF. | |
| Thiel Owners Beetle - I suspect the "don't do it" is because the spuriae introduced are evidence of non-linear behavior which can cause problems for some amplifiers.Rob - the only resistors that benefit from upping are those carrying current, which are in your... | |
| Thiel Owners Rob and Beetle - I have also gone back and forth between wire configurations. My observations are similar to both of yours, the parallel configuration seems to add dimension and space. I hear more lucid harmonic detail such as obviously double str... | |
| Thiel Owners Insider information: I've been told that Jim and Gary listened to every cap out there, along with measuring to choose the ClarityCaps. At the time the SA was top of the line. I've compared the SA to the CSA. The CSA is next league. Truly remarkable. |
