Notice that each midrange driver has an edge closer to the listener and an edge further from the listener. That's "what the hell I am talking about."

Don't forget that the radiators aren't a point source, so don't approximate them as such. For those frequencies where their dimensions exceed 1/4 wavelength, you'll have a bit of a problem. You'll need to solve for them using an array of radiators as your closest approximation.
Please post your models!
