This is sort of a "preliminary" post, to air some of the thoughts that will lead to my next disaster, which I will tell about once I begin to get some actual results. My thinking is still about the same as it was when I made the 11-01-09 post; but some of the ways I have been thinking about the results themselves have warped a little over time.
Basically, I have pretty much floundered when it comes to the subject of crossovers. The hellovitt is that speaker level XOs are the devil's tools. Despite what one thinks when plotting them out on paper, they are actually moving targets, in every sense of the word. Further, especially at lower frequencies, the very nature of the XOs themselves makes it almost impossible for the amp to do what the XO math says it will do.
While I was thrashing around on this subject, I may have caught a small break. I forget exactly what I was looking at a couple of days ago, but a link came up, and that led to another link, to Dick Olsher's site, where I found some ideas for much simpler XOs for speakers much like my own DEBZ; Dick gives all "updates" to anyone who's purchased any of his plans, at any point, and he sent me some more specific information to put in my XO oven. If the examples I got from Dick are not perfect for my own situation, yet they are of the right stripe, and it certainly got me to thinking about ways to try to get some of what I am after with drivers I already have, using mostly parts I also (ahem...) happen to have "on hand".
This post reminds me of those guys on TV, who yell and pump their fists before they ride a small bicycle off a roof...
