Thiel Owners

Pass Labs is a sonic match with Thiel loudspeakers. Keep us posted after you talk with Kent or Mark.

Happy Listening!

Regarding the outboard filter:  i have not tried it but i did write Rob about it around a year ago and this was his response: 

Hi Kent,

 

This is very interesting. It is my belief that the crossover has been tweaked by Jim Thiel, to maximize the frequency response of the coaxial driver. These additional parts would change the impedance, as well as the intended phase and time coherence of the speaker. This sounds like a fluke. I think this is just someone trying to benefit from the closing of THIEL Audio. I am guessing that for $95, the parts are of low quality, not to mention, the effects that it would have on the amp and speaker.

About a year ago when I was re-exposing myself to the State of Thiel, I called the guy offering this filter. I judged that he is seeking to smooth out the measured upper midrange squiggles without understanding the nature of those squiggles as low-level reflections from the driver geometries, and therefore in the time domain. I agree with Rob that the "fix" would harm the sonic presentation in Thiel terms of fidelity to the input, even though his frequency response graph would look smoother. 

Thank You Ron and Tom for shedding a little light on this subject. I suspect many of us here have viewed that ad on eBay and questioned its effect against our loudspeakers. Hope you guys are well today and enjoying the music.

Happy Listening!

I would be interested to know if anyone here has evaluated the filter. My opinion is extrapolated from what I see and what he told me - I haven't heard it. Anyone?
