Thiel Owners

GENERAL QUESTION TO EVERYONE:

I bought a pair of genuine Thiel Outrigger stands, but the Ebay seller doesn't know what model they fit. The front two spikes are 13-3/4 inches apart, from center to center . Does anyone know which model(s) speaker they were made for?

Rules - keep up the good work and keep us posted. Yes, the variability, especially with operating temperature, but also with elapsed time and use all require assumptions of what is average. We called that "average operating condition" as 1/2 hour into fairly vigorous playing. Note that the flat impedance curves created by the Zobel filters do a lot to minimize impedance variables.
I suggest more study on minimum vs linear phase. Minimum phase characteristic is where phase follows amplitude as each driver rolls off. The trailing phase and amplitude of one driver is inverse to and cancels the leading phase and amplitude of the other driver and nets to zero. Linear phase does not zero out and results in ringing in various ways depending on the type of filter.

"Meadowlark seems to be back:’

Interesting that they are no longer touting time/phase coherency the way they did back when they were doing passive speakers. I’d guess perhaps they are still trying to achieve it via DSP, but if so it’s weird that they don’t mention the time/phase coherency results.

Prof - I noted in their website talk that they are using high-order DSP filters, which do not produce phase coherence, although all the talk implies that they do.

In my music production consulting work, I routinely picked out edits in mixes by the pre and post ringing of high-order DSP filters, while listening through (coherent) CS2.2s. The producer would invariably respond that "you can't hear that", usually because of his $7 figure equipment investment and grammy awards. But I and my client could independently spot the edits and other anomalies by separately noting time-code.

I don't claim to know what Meadowlark is doing. The review I found of the Swift shows wildly ranging impedance and phase swings - but it is time-coherent. The Shearwater qualifies as a T/P coherent design.
