| Thiel Owners audiojan - nice system. I do have a reservation about the Bel Canto. The site states minimum impedance 3 ohms. Some class D amps hit a brick wall at their minimum impedance. The CS2.4 drops to 2.73 ohms at 600 Hz. I wonder if you might be running ... | |
| Thiel Owners jon- Rob Gillum at CoherentSource Service makes the PXO modification to match the Thiel speaker of your choice. audiojan- your experience is classic: distance from the walls makes for better image and evenness, but those very walls were reinforcin... | |
| Thiel Owners kdross - congratulations on your CS2s. Thiel made more of those than any other model. It is possible that the loud levels did the damage if fed by an amp with insufficient power to deliver a clean signal. It is unlikely that the woofers or any of ... | |
| Thiel Owners Ish - Duh. I believe the SSs are all analog, so delays and so forth can't be easily implemented. For example, dsper's upper and lower mid drivers needed 3/8" and 1/2" time delay which took, if I remember correctly, more than 40 bucket brigade capa... | |
| Thiel Owners ish - I am interested in your SW1. Please contact me via PM.Regarding the boundary management software, I would only be guessing. I do know as you outline, that Jim would not have addressed the problem via EQ. I believe there are patents on what h... | |
| Thiel Owners No. Lobing is inherent in first order filter slopes; it has to do with additive phase physics. If one tried to massage or average the lobed output, it would adversely affect the power response. However, the sloped baffle (rather than discrete step... | |
| Thiel Owners Unsound - the dispersion at the midrange upper end is narrower than the tweeter's lower end. The wave guide creates some directionality at the low end of the tweeter to better match the midrange for smoother image projection vs frequency. They wer... | |
| Thiel Owners Bray - what is the difference between the SS2 and SS2.2. What is your "late model" serial number? | |
| Thiel Owners Bray - I only know the broad outlines from observations and a few conversations. The SW1 came out in 1997 from work Jim had been doing for about 5 years. That was early Class D and incorporated thermistor compensation and shaping circuitry ; the S... | |
| Thiel Owners Add to the 2.7 development team: Gary Dayton and Lana Ruth. The design engineering firm was Warkwyn, Ontario. I think the lead designer was Tim Gladwyn. The 2.7 XO is very different from Jim's 3.7 XO. I hope to eventually learn enough to report on... | |
| Thiel Owners Jay - when Rob had access to the New Thiel cache when they were closing the Nashville facility, he reported that 3 pairs of the series had been sold. There was inventory, but I don't know how much or what became of them. Rob didn't bite. | |
| Thiel Owners Prof - thank you for your appreciation. The "live with" factor was an integral part of our designs.Jay - there are two periods of post Jim Thiel designs: the x.7s including the 2.7 and 1.7 and the MCS?.7 prototype. The physical CS2.7 was principal... | |
| Thiel Owners First, thanks for the jostle of other phase coherent brands. It also seems that some ultra-expensive European brands are honoring the time domain. (Reminder: engage brain before responding) Cheers.Regarding grille and grille frames - they, like ot... | |
| Thiel Owners Most of you have identified phase coherence as a necessary ingredient for "reality music", rather than the hi fi approximation. As far as I know, Vandersteen is the only maker other than Thiel who produces actual minimum phase speakers. Their bias... | |
| Thiel Owners unsound - I agree. I don't know why Jim designed for such low system impedance. I can speculate that marginally lower distortion in the driver motor may be had via lower driver impedance . . . BUT all the amplification problems caused by low imped... |
