If you get paid by the word, I owe you big time! Your comments are very helpful, indeed. Thanks. I am particularly intrigued by your recommendation of bass panels. Hmm. Do they add a significant variable with respect to their placement? It sounds as if they actually make things simpler?
Thank you again.

Bass panels are certainly a new paradigm in audio. I think there is a strong argument for multiple sources of bass, hence the opinion that multiple subs is a good thing -- you can get more power, more evenly distributed into the room.
I believe the DWM taps into the same principle, within reason for mid and upper bass (mine poop out under 63 hz). It is hard for me to get my main panels to play evenly as desired across all bass frequencies in any one position*. Even worse, the place with the best and or most even bass is not the same place as best for everything else. Not even close.
The DWM panels, allow flexibility, though it probably makes things more complicated, not less. They can be adjusted via resistors and such, and small changes in relative distance to the listener, to the mains or to the nearest wall make large changes to frequency response from 63 to 250 hz. It makes it possible to tailor the bass to taste and or to smooth it out. They can eliminate nulls and in some cases even reduce peaks. They certainly allow much more power in drums and bass.
That said, you can't put them just anywhere, especially in a shoe box shaped room. If they are not roughly even to 24 inches closer to you than the mains, they can screw up the lowest mids and do some phasey comb filtering things. Oh, they also require a small separate amp or the ability of your current amp to play at 2 ohms.
I would strongly caution anyone considering DWMs to do an in house audition first and to NOT expect them to sound good without moving the main speakers (which have been optimized already for no DWM). They are not subs.
* does anybody have success with getting ideal bass and ideal everything else from a single pair of Maggies? It would be interesting to hear from others. My experience is it is all tradeoffs.
The bass is ideal in my room in two locations along the 20' sidewalls - about 8.5 ft and 11' and change. The intermediate locations between them have less powerful bass but it is still way better than closer to the front wall. Entirely acceptable to be off from the ideal bass spots. The front position does the whole Limage thing spectacularly, but has "head in a vise" issue, the soundstage is preserved as you go from the 11' to near 10' and starts losing depth and falling in scale from there.
I am ggoing to try the split position again with the bass panels at the 8.5' position and the mid/treble at the 10'+ to 11' position. Will have to work out the XO for that - will probably just use the Rane for bass LP and adjust phase. The LP would be 4th order then.
