| Thiel Owners 8th-note - gotta go soon, so you get the short answer. Do some practicing with a vacuum cleaner and then pull your dent out with vacuum. If you don't hear voice coil rubbing, you're not doing damage. When it's as smooth as you can get it, put the ... | |
| Thiel Owners Although I and Kathy were integrally part of the early decisions, directions and perspectives, it was Jim who took the bit in his teeth to create the electro-acoustic solutions. And he got better and better. My chief contribution was building a co... | |
| Thiel Owners Sdl4 - very well stated. There exists an arrogance of intelligence which imagines it knows everything when it can explain anything. Thiel's founding attitude and guiding principle was that we only understood a small corner of what we were dealing ... | |
| Thiel Owners JA - On to your question. Our first speaker wire, including the 1978 CES where we introduced the 03, was home-brew made from #0 stranded welding cable configured for lowest conventional problems. It measured well and looked impressive. Jim was al... | |
| Thiel Owners JA - thanks for the link. I'll cover some ground, perhaps repeating some stuff from previous posts. Wire was an essential element in Thiel's adoption of first order coherence. We sweated blood for a year and a half in 1977 - 1979 to decide to adop... | |
| Thiel Owners Sdl4 - this discussion fits a template deeply ingrained in the mainstream engineering community: if you can't prove it, it's not real. The article is embarrassing, but beyond that it doesn't explore much of what Jim knew because Gene wouldn't admi... | |
| Thiel Owners JAFant - would you please supply a link to the Olsher article? I didn't find it searching the Absolute Sound site. | |
| Thiel Owners Rules - you may be interested to know that Jim's 2nd choice was 2nd order. The 01 had been 3rd order, the 02 was second order, but not inverted polarity like Wilson, but rather both drivers in positive polarity with the X points fudged to lower th... | |
| Thiel Owners Rules - my comment addresses the presumption among many that zero or linear phase response is without problems. I admit that its problems are indeed minor and in the real world may be a best choice solution. For your enjoyment here's a very brief ... | |
| Thiel Owners Prof - I noted in their website talk that they are using high-order DSP filters, which do not produce phase coherence, although all the talk implies that they do. In my music production consulting work, I routinely picked out edits in mixes by the... | |
| Thiel Owners Rules - keep up the good work and keep us posted. Yes, the variability, especially with operating temperature, but also with elapsed time and use all require assumptions of what is average. We called that "average operating condition" as 1/2 hour ... | |
| Thiel Owners Beetle - Thanks for the reference products. Jim did control out of band problems as you say. However, his major tool was to create mirror circuits for the relevant troublesome resonances - electronic anti-resonance circuits if you will, which canc... | |
| Thiel Owners Unsound - thanks for the links. Indeed direct drive could be awesome with today's technologies. As I've mentioned, active was our starting point in the mid 70s. Wish I could find that first crude research speaker: 10" 3-way with 3 home-brew amps a... | |
| Thiel Owners The difficulties of T/P are substantial and the prevailing wisdom from Canadian Research Council, Harmon, etc. is that the ear-brain doesn't care. We here lean toward the opposing opinion. And I am personally convinced that T/P as executed with fi... | |
| Thiel Owners As candidate drivers are identified I and/or Rob can vet them. Rob is learning to use Thiel's Klippel and I am learning to use my SpectraFoo to make critical comparisons between the design driver and potential replacements. I recognize that this t... |
