As the Irish say..."Is this a private fight, or can anyone get in?"

My only comments are:

#1) Computer simulations are a wonderful (and expensive) thing. But NOTHING can take the place of a real box with a driver in it and your ears.

Which leads me to
#2) Quit wasting time on computers and get behind a table saw and build something. Particle board and mdf are not nearly as expensive as software.

Listen to what you've built for a while. If you eventually find you don't like it; take the drivers out, burn the boxes and build a different design.

You'll learn something and your cabinet making skills will improve!
