Thiel Owners

yeti- I don't have torque values, but I do have some thoughts. Wood products (MDF) hold screws well against vibration; more exotic baffle materials require threaded inserts. I don't know the 1.6. Metal to metal threads are prone to vibration creep. I personally put a dab of Permatex type 2 (non-hardening) on the thread before torquing to taste. There are other brands and types of non-permanent thread goo at the auto parts store.

Add: tight driver screws make a surprising amount of difference in resolution.

Tight connections are a must, but be careful, I’ve seen Thiel’s with stripped driver screw mountings due to over tightening.

Of all the speaker manufacturers currently on the market, which company would you say whose products are most comparable to Thiel? 

As for time-coherent, Vandersteen probably comes the closest but the sound is a bit more should I say warmer?
I can't really think of any brand from the top of my head.

@andy2, I've been wondering that myself.  For those of us who mostly use digital playback I think the ultimate setup will use digital/software crossovers that can be switched to whatever you want.  Heck, my 12 year old Velodyne sub has this option.  You can choose any slope from 6 to 48db/octave.  There is a built in digital equalizer, etc.  They aren't the only ones to have done this.  DEQX is still around and does everything digitally.  I don't think they provide the option for phase correct 6db crossovers right now but I'm pretty sure they could if they wanted to.  It's just software.
