This will probably be my last post re this particular situation.
I just want to conclude that the chances to make the sound worse by continuing down what seems to be your chosen path is much more likely than it is to improve the sound.
While it is really none of my business, why are you seeming so dead set on forcing your setup to a biamp configuration?
If you can't tell, I'm really trying to discourage you from tearing apart your speakers and buying a bunch of stuff that, in the end, has a high possibility of sounding worse.
