| Thiel Owners Rob - Thiel's wire was developed in the late 70s through our contact with an aerospace avionics engineer (cousin Ted). For many reasons we settled on OFHC polished solid copper in teflon jackets with a tight 3/inch) twist. Wire carries competing p... | |
| Thiel Owners Fitter - I got the chance to compare CS7s with 7.2s when I visited Rob G at CSS last Thanksgiving. What a treat! I judge the 7.2 to be more concise / articulate, but he and I both liked the 7s better, as more easily listenable on more material. Th... | |
| Thiel Owners Rob - I’ll get some measurements on my various wires. However, the resistance is not the whole story. In fact, audibility is a result of many factors and many of those are phase related. Two parallel tracks. A: lower resistance will change the fre... | |
| Thiel Owners Stspur - thanks for your report. I am interested in further sonic developments through time. Let us know what you hear. | |
| Thiel Owners GS - no definitive answer. Check with Rob G at Coherent Source Service. Photos may be required. Generally speaking, the high mass of that baffle precludes much movement in use. Shipping ? If mine, I would consider an expansive hydraulic grout or c... | |
| Thiel Owners Masi - my suggestion is that you are doing well with sspur. Also, this forum has lots of information going back a few years with answers to lots of your questions - and there are people here with first-hand experience to guide you. I have not form... | |
| Thiel Owners Rob,Is your wire a single twisted pair of 17.5 per leg? | |
| Thiel Owners It's probably caulk - I don't know what kind. In my time we used acrylic latex painter's caulk with good results, and sometimes hotmelt adhesive to build a mound. But, sealing was always be a big hassle; hotmelt and caulk are both permanent, which... | |
| Thiel Owners Rob - I will be most interested in your 15.5 to 17.5 gauge comparison. | |
| Thiel Owners Rob,,Sealing between the chambers is important for impulse integrity. If open, the woofer air pressure yanks the midrange around - not good. You can temporarily seal well enough with Mortite or bowl putty. When I came to New Hampshire in 1996, we ... | |
| Thiel Owners Rob - I saw and heard the first pair of 2.7s at the factory in 2012. I believe there was an angled dividing board between the lower (woofer) and upper (midrange) chambers.I should add a thought to the insulation riddle. Many people assume that woo... | |
| Thiel Owners For the record, wool acts quite differently than fiberglas, as does polyester fiberfill or spun mineral wool, especially in transition to the deep bass. Final placement and voicing of damping was always made by results. Listen to it, and if you ha... | |
| Thiel Owners I see. Small trace sounds suspect. I've exhausted my clues. I have a PP XO schematic - same drivers, if that might help. Try Rob. | |
| Thiel Owners Jon - your pic shows PC boards which are all too easy to burn.PM sent | |
| Thiel Owners Jon - I haven't had your experience, but I can comment.Broken leads are usually caused by excessive excursion.Your 2 volts AC at the tweeter and woofer with a 60Hz test signal is improper. Tweeter should be near zero.Caps and resistors usually blo... |
