first of all, my equipment: 2 12" AA Arsenals (rated for 750 rms each) pushed w/ a kicker kx1200.1 (actually 1440 rms)

I am using this port size calculator
( http://www.the12volt.com/caraudio/boxcalcs.asp#por ) and have a few questions:

do i need to factor in the driver displacement when entering my box volume?

my port will be a slot port. So all i do is come up with a rectangle with the same surface area of the circle. anyways, say my slot length is to be 20 inches, which board should be 20 inches, the red or the blue? i would assume the red but im not sure.
