| Thiel Owners Devin - Thiel crossover schematics state the max tolerance of each cap. Some are 5%, some 10%. Among the strategies, I prefer to try for close to equal values when splitting. I've learned end-reversal via trials. E-caps are fundamentally symmetric... | |
| Thiel Owners devin - Replacing like with like components is certainly the safest. Many folks underestimate the intricate co-dependence of all the elements. Even layout changes affect the subtle outcomes. Keeping values at original levels is a good start, but v... | |
| Thiel Owners Beetle - our project was good both ways. Thank you for your careful and complete evaluations and reports. Even though we both think that you got seriously upgraded performance, there are actually big gains to be attained with less expenditure. One... | |
| Thiel Owners lars - a few thoughts. I have rather recent acquisitions of both CS5i and CS2.4, but not much actual experience with either of them. I’ll jump to my conclusion first which is that the 2.4 might well suit your needs better due to what may be your f... | |
| Thiel Owners devinplombier - we did explore low level crossovers. Net result is that we knew our niche which was all analogue and purist. Other folks have done versions of what you suggest. We always looked at overall cost effectiveness and separate amps, cabl... | |
| Thiel Owners duramax - I'll be happy to ruminate on the CS5 baffle. The CS5 followed our 1987 CS3.5 which was a runaway hit, and our most expensive product to date at $2450/pair. Times were good, the market was hot and many manufacturers were presenting $20,00... | |
| Thiel Owners devinplombier I don't know much about the Apogee line across the board. There are other high-end brands and models - Wilson Watts come to mind - that are have treacherously abrupt impedance swings with sub-1 ohm bottoms . . . and advertising that... | |
| Thiel Owners devinplombier- The CS5 and 5i are identical in their requirements. The only difference is the 5i has woofers that Jim improved via incorporating his motor shunts and focused gaps, which do not change power requirements. The Apogee line, as I ... | |
| Thiel Owners I'll vouch for the 1.2 as being the first second-generation Thiel speaker. It preceded the CS5 and as such was the working trial for our first copper motor shunts, and aluminum dome tweeter. This was the first product to benefit from our investmen... | |
| Thiel Owners Yep - those 48 strands work out to 25awg good to 85kHz saturation / 2 for layup loss. All good except. My quibble is that a tweeter works around 5 watts for negligible current demand. Meanwhile that entire conductive mass must be charged and disch... | |
| Thiel Owners devinplombier The role of audio wire/cable has been routinely underestimated by mainstream engineering. However, in aerospace and now in high-speed digital technology, wire has risen to the status of a system-limit - and therefore importance. The... | |
| Thiel Owners Hi Tom - Lots of experimentation and solid results. No viable manufacturing capability yet. The wire / cable journey has been a very deep dive. My solution is unique, effective and manufacturable. I have benefited from Ray Kimber, Mike Morrow, St... | |
| Thiel Owners Andy - I have no inside information. Rob is in a difficult time with his failing mother. CSS is viable. | |
| Thiel Owners Jim - You are correct, the EQ circuit boosts the bass starting at 300Hz to 12dB at 25Hz. Our initial intent was to EQ the woofer and leave the midrange and tweeter unaffected, but the slow XO slopes required grouping the woofer and midrange to kee... | |
| Thiel Owners andy2 - Here's some history. The CS2.4 coax was designed and built in-house and tested with our custom rig. Rob Gillum participated in and periodically supervised the manufacturing process. Rob's rebuild includes replacement of the moving system... |
