| Thiel Owners Rosami - there are hypothetical failures which could damage a driver. Other DIYs here might know specifics. A feed resistor on the tweeter, or even midrange, could short rather than going open (highly unlikely). Such failures would usually be visi... | |
| Thiel Owners Rosami and Jon and all - Yes, there are various new crossovers and yes, what is being learned on the 2.4, 2.2, 1.6 and PowerPoint all applies directly to the 3.6. And I have a pair of 3.6s on hand. My present work includes developing my measuremen... | |
| Thiel Owners Holco - Thiel used Jantzen and ERSE wire coils as equivalents.I have ERSE foils on hand and some Jantzen Wax on order.I will compare them directly, but not yet. | |
| Thiel Owners The 2.2 bass was our first passive radiator and as such it coupled to rooms better than anticipated and came out slightly under-damped and somewhat (1.5dB) higher in level below 200 Hz. It has the fullest bass of any Thiel product, which was warml... | |
| Thiel Owners Beetle - a 3.7 upgrade is quite straightforward since the drivers are so well behaved, there is not much circuitry in there. The tweeter caps could be upgraded to CSAs with perhaps an ultra bypass around the 1uF styrene/tin. Electrolytics to film ... | |
| Thiel Owners Andy - I second your motion. As car guys say, the least expensive option is the one you have. So if you have 2.4s, then upgrading resistors and caps is a huge bang for the buck. I concur with the 2 sub solution. The CS2 - 8" woofer just can't move... | |
| Thiel Owners Bighempin - if you contact Rob re the cap / nacelle on the 3.7, you might also ask the following: Does he know the serial number breaks for the 3 versions of the 3.7? I have developed XO schematics for the original, revision 1 and revision 2, but... | |
| Thiel Owners RonKent - Re: "hi Tom, thanks for the clarification on phase, absolute phase, and all those other phase things."To clarify, you did not err in your vocabulary. The term "phase" is applied widely to both matter of phase and matters of polarity. I... | |
| Thiel Owners ronkent - that live album at Stony Mountain is a normally produced remote recording, pretty good as they go. Her studio albums have higher audiophile values. Above I described the first Dancing at the Gate, later Will Ackerman produced Color of Li... | |
| Thiel Owners Phase is used to mean different things. The signal reversal that ronkent mentions is actually polarity, where the entire signal is switched plus for minus. That is straightforward to troubleshoot. Put a 4 volt DC signal way up front in your signal... | |
| Thiel Owners Todd - I mis-spoke to a degree. Much of the best modern equipment is phase coherent, but there is plenty of gear that employs global feedback, steep filters, etc. which introduce phase anomalies at super-sonic frequencies, which are known by some ... | |
| Thiel Owners Reference Recordings are completely phase correct, as is your playback chain unless there is a wiring error. So the signal at your speakers is phase coherent and if the speakers keep it straight you can hear that proverbial pin drop. Enjoy. | |
| Thiel Owners Kent - Yes, precisely. Jitter is timing errors which were believed by many to exist beyond human hearing, because when translated into the frequency / tonal domain, the artifacts are beyond the audible range. The auditory brain must work hard to w... | |
| Thiel Owners Hi Kent - Dana's music comes from that place we all want to go . . . it goes by names such as life and love, and sweet inspiration. Her inaugural album "Dancing at the Gate" is in many ways my favorite. One small piano in one small room with one p... | |
| Thiel Owners Ekohn - They're not bookshelf, but you might consider PowerPoint1.2s. They are wall or ceiling mount, so they take no floor-space. Same driver as the SCS4 in an aluminum wall-mount cabinet. Their configuration minimizes boundary effects for extrem... |
