Hello;
I have not tried to fool my EQ setup, I didn't seem to have too much trouble with it. My problem is sub placement. I have a huge hull around 50hz. That has kept me focused on different stuff.
The only reason I brought it up is that I'm in the software bussiness and sometimes people will write very robust code for situations that aren't in the spc so to speak. In the last two years I have been working with HW very closely and for various reasons (code size, complexity) the hw guys code for spec and spec only. I was figuring that the code that does all this stuff might be designed for the specific setup and might not clear itself if the speaker config changed after the eq was done.
Good luck
