Thiel Owners

sdecker - tilting is the less offensive solution. But the changes introduced by either tilting or lifting are very small and either provides better performance than listening at the 'wrong' window. The coherence puzzle has its requirements, and Jim chose the average 3' ear height as part of the solution. The window is not as small as some imagine it to be unless you sit closer than 8' where it falls apart very quickly. Sit at 10' and you get a lot of leeway.

   I now realize what I've been misinterpreting for fifteen years.  The infamous Stereophile measurements are taken at 50".  Their 2.4 test figure #5 "vertical response family" shows the 1kHz crossover suckout just above the tweeter axis. 
   So at my 9' listening position vs their 4' measurement position you suggest I have far more leeway for vertical response, even though my 38" listening position is only 2" above "ideal."  Whew.
   I can't understand how JA's 50" measurements correlate to the real world for any speakers but pure-nearfield mini-monitors, regardless of XO design or driver spacing, especially the large multi-ways they typically test.

Coherent speakers must heed the listening position to test properly. JA knows this. His normal, small room would add too many early reflections to give readable graphs. So he chose 50” which gives false readings for coherent sources. There are other review rags using more legitimate methods. 
Early on, JA explained, even apologized for the misleading readings. But subsequent ownership policy changed that.

your 38” at 9’ is fine.

Looking to replace the damaged mid-range in my Thiel CS3.5 speakers.  PBN Audio recommends the Scanspeak 10F/8424G 4” as a replacement.  Apparently no modifications to the crossover are required.

 

Has anyone heard the CS3.5 with the 10F/8424G?  If so, can you describe the sound? Power handling long term max power of 30W and a relatively low 400Hz crossover seem OK?  This is reportedly a most outstanding driver.   Do you think it is an improvement over the original mid-range driver?

Moved this question to the Thiel Forum.  Hope it's in the right place.   Thanks.
