| Thiel Owners Prof - "well" is such an interesting and loaded term. For years I have been pondering what makes some systems sound so "right" and others, perhaps technically more advanced, sound less right. One idea that keeps popping up is at the core of what w... | |
| Thiel Owners Welcome back brayeagle. From the other end of the upgrade lens, I just snagged a pair of 02s in near mint condition for $210 delivered: 0687-0688 (around 1980) from one-owner in Michigan. Cabinets never opened, parts all look new, the improved-con... | |
| Thiel Owners Unsound - my apology. Indeed adding an amp and cables is a huge expense. My thought is with used market prices such an upgrade has potential to raise the performance level of the 5i a lot. And more to the point, the CS5i's difficult load practical... | |
| Thiel Owners Unsound - Regarding impediments to CS5i ownership, I am confident we can address the primary shortcoming quite easily - and that the amplification problem would be reduced significantly. The impedance drops to 1 ohm in the deep bass and doesn't ri... | |
| Thiel Owners Power recommendations are really sketchy, since the manufacturer doesn't know your loudness requirements or room size which are the largest factors in the equation. Regarding the sensitivity increase, I remember that driver refinements allowed low... | |
| Thiel Owners Rules - I believe that your undertaking will be of great value to Thiel fans. The 3.5 was a pivotal product in Thiel's emergence; but it has lots of room to grow. The cabinet is a significant piece of technology, so re-outfitting its DNA for a new... | |
| Thiel Owners Unsound - right on! In fact, the model 2's reason for being was conceived as just that - create a huge bang for buck product utilizing technologies and parts whose development costs were amortized at the higher-end. In the beginning . . . Jim was ... | |
| Thiel Owners Prof - the 02s were made from standard-grade stuff, miniature, standard electrolytic caps,5w carbon comp resistors and normal coil wire. The system will often work with bad parts. At nearly 40 years old, the caps are almost certainly shot, unless ... | |
| Thiel Owners Andy - regarding diffraction - please pardon me not knowing its controversy, I've been out of the loop too long. It is not controversial nor trivial, it is a fundamental element of design; it is measurable and directly hearable if the system is tr... | |
| Thiel Owners Prof and you other 02 fans - I just now got my old 02s on line - received from my brother from their life-long use in our parents' system. Drivers are good, coils are good - within their genre. These speakers were made in 1978 before we discovered... | |
| Thiel Owners Prof - Cabinet stiffness including the baffle helps it disappear. I am experimenting with "stiffening" the MDF cabinets, especially the driver mounting recesses with Minwax Wood Hardener. Also that 3.7 cap is far quieter than the 2.7 top. I am ext... | |
| Thiel Owners Unsound - everything matters, and there may be some effects from the forward parts. The cross struts are 1/4" diameter round bar, and not in the path of any drivers. The forward side verticals are 1/2x1/2" MDF, but so far off axis that they presen... | |
| Thiel Owners Andy - the baffle is critically important for how the waveforms propagate into the room. Going back in history, common wisdom dictated the drivers be offset by differing amounts from all baffle edges so as to spread the diffractive effects out, ov... | |
| Thiel Owners sdl4 - an outsider you might consider is Morrow. I ended up outfitting my studio with Morrow ICs and speaker runs. My comparisons weren't terribly extensive, but I did read widely and compare against some old Kimber, Straightwire, OCOS, Mogami, MI... | |
| Thiel Owners Guys - we have learned enough to repeat the successful upgrade that Beetle performed. But we have not yet approached the comparative analysis to find cost-effective performance points. Beetle-level parts cost would exceed $1K, and parts cost is no... |
