In my meager experience I would agree with Duke and others about the crossovers. That is truly where the art meets the engineering and can make or break a speaker system.
I have gone down the same path that Wireless' friend traveled. It is very easy for a DIY'er to do because we are limited in what resources we have available. So the tendency is to get the best looking specs whether they be simulations or RTA plots. When it comes to the crossover, the best resources to have are good and varied ears to help listen and give feedback. I can do Pspice simulations all day but none of them will tell me how it is going to sound. There is no way around this if one is striving for the best they can achieve. At this point all of the numbers have been used up. Now it is time to decide what sounds the most realistic by using your ears.
