| 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... | |
| Thiel Owners The Dynaudio tweeter was a D28/2 - 6 ohm. Rob has been looking, and is continuing to look for a drop-in replacement. Keep us posted on what you find. | |
| Thiel Owners Sandy - Here's a recap of model strengths and upgrade strategy. I hope those interested find value and that others can allow an old man his remembrances. The model 3 was our first best guess of addressing the most things required of a loudspeaker.... | |
| Thiel Owners Sandy - I'm having fun sharing this stuff with you all. You're on it - most speakers scramble time / phase, sometimes by many hundreds of degrees. The ear-brain does a commendable job of reconstructing those wave-forms into intelligible music or s... | |
| Thiel Owners I'd like to share my thoughts regarding spikes; I performed the investigations way-back which led to our incorporation of spikes in the CS3 in 1983. As Sandy said, the chief problem is recoil. The effects, however, depend greatly on the floor syst... | |
| Thiel Owners The radial wavy plate midrange of the x.7 presents a better launch-pad for the center-mounted tweeter than does the previous midrange cones. The cone double diaphragm allows a much shallower front profile than standard, and is therefore more benig... | |
| Thiel Owners Sandy - I hope that name is OK, since that's your hi-fi identity to me. I credit Harry Pearson with creating high end out of its hi fidelity foundation. Hi Fi had been generally academic, formal and engineering driven. Hi End was generally young, ... | |
| Thiel Owners Correction: the CS3 was introduced at the Chicago Summer CES in June 1983, which is part of the 03b story. | |
| Thiel Owners Sandy - thank you for your remembrances. The 03a was the real beginning of it all. It upgraded the 03, which was Thiel's shortest run in history: one year. The 03 was our first product to address time / phase with first order slopes. We struggled ... |
