I get a "page not found" error in the link at the post that you linked to.
Is the bottom line of what you are saying about this, that one should take in to account the entire system and not just blindly believe that some crossover topology, order, etc. is "best", or something like that? Meaning that the phase has an effect on the summation, lobing, etc?

All the links seem to work OK, I just tried them.
The bottom line is that all aspects must ultimately be taken into account in designing the complete system. A crossover topology should be chosen that does not have uncorrectable flaws and offers a reasonable expectation of being able to successfully implement any additional correction circuity with a minimum # of gain stages. Before additional correction can be calculated, an accurate understanding of the fundamental nature of the crossover topology is essential. Compounding errors upon errors in hopes of obtaining a workable solutuon seems unwise.

Looking back at some of your references, the problems associated with vertical lobing seem to be of most consequence in large theater situations. Compared to other response anomolies, how relevant is vertical lobing in a typical home environment where there is little or no vertical change of the listening position and where there will probably be a moderate degree of sound absorbtion from the furnishings (carpet, drapes, sofa, etc)?
This sounds like jumping in the deep end over your head.
If you think that lobing is not a problem, try the stand up sit down test you may find your head in the null.
