| Thiel Owners JA - one dovetail of the XO project with my musical instrument work is that I use the same listening, mic, software and equipment setup for both purposes. So, I am taking measurements while making the guitar, and making archival recordings for lat... | |
| Thiel Owners Hello Sandy - good to see you here. This forum is my sole on-line activity. My experience tracks yours. In all the years of demonstrating and exhibiting 3.5s, we (Thiel Audio) NEVER blew a driver, even when purposely tempting fate with high levels... | |
| Thiel Owners JA - the disciplines are related and knowledge usually cross pollinates. But my goals in Denver relate to acoustic guitar and piano design. Making the music is my heart's delight. | |
| Thiel Owners Hi guys - just back from the soundboard voicing masterclass in Denver. Physics rules the technical arts. I'd like to affirm these recent comments about the 3.5 and the progress of Thiel's models in general. As this inner circle understands, the go... | |
| Thiel Owners Rules - zero phase rings before and after a transient event. Minimum phase does NOT ring. It's worth some study | |
| Thiel Owners On a personal note, I will be traveling and out of contact for a week. I am attending a master class in soundboard tuning from the Australian physicist Trevor Gore. My primary occupation is designing stringed instruments and Gore's pre-retirement ... | |
| Thiel Owners Rosami - no firm news. The bankruptcy is still pending, so I am behind a curtain. I can say that I am enlisting talent to augment my limited abilities. I can answer your question regarding hot rod kits. Some general recommendations will flow (and ... | |
| Thiel Owners RW - your story strikes the core of our inspiration to "do speakers". Thank you for sharing. That emotional connection you reference is what we identified at the core of the minimum phase presentation. I have subsequently studied aspects of audito... | |
| Thiel Owners Integrated amps have evolved indeed. What strikes me about rwmeditz's experience of "holographic image" is how the impedance difference of the 2 speakers might be operating. The 3.5 bottoms around 5 ohms from 100 to 1K Hz with rising lower impedan... | |
| Thiel Owners rwmeditz - I am interested in your further comments and comparisons about 3.5s vs 2.2s. I am familiar with both, but don't have 3.5s for comparison and hope to align my analysis of pieces and parts with your sonic / musical experience. Please ela... | |
| Thiel Owners George - thank you for this post. I used the 2.4 spec in error. The germane point is that Thiel's Passive xo does not attenuate the main speaker's low end - in this case a little below 35 Hz. | |
| Thiel Owners J.A - Thanks for asking. Good progress re comparative listening and measuring tools. Great appreciation for Jim's component choices within his budgets. I'm presently testing various mechanical upgrades: cabinet stiffening, stiffer driver mountings... | |
| Thiel Owners George & prof - I think the low-pass 3dB down point should be @ 45Hz, the natural 3dB down point for the 2.7. There is no high pass / low cut filter in the XO, so the sub crosses to the woofer at the natural bottom rollin of the woofer. | |
| Thiel Owners George - I use PX02 and PXO5 crossovers rigged for each model. They create an inverse of the roll-off characteristics of the speaker, therefore creating an ideal match by definition. That solution was patented. It seems to my ear to work very well... | |
| Thiel Owners CS2 guys - welcome to a remembrance. The CS2 is among the most successful and most formative in Thiel's history. The 3-series launched from near the beginning; the CS3 was 4th generation thinking in 1983. The CS2 was a fresh start in 1985. It was ... |
