sd, I have a question regarding your post.
You say I am heading towards more absorption vs dispersion. Is this due to me wanting to insulate the walls and ceiling? Please advise if you don't mind.
The room is just over 22' deep. Would you agree I have enough room to pull the speakers off the back wall to yield better bass response?? Or do you think my room is still too small??

Sorry, just re-read your post more carefully and I think I misunderstood sound isolation and sound proofing for also trying to have a less reflective room. I fully agree with the notion of sound proofing (we did that through double studding and double sheetrock and heavy oak doors). I also did a wooden floor over concrete and added thick wool carpeting.
As to room depth and pulling the 3.7's off the back wall, I think you do have enough space (but that's where I'd be tempted to run the REW software to test where you are likely to create reinforcing reflections). What I tried to do was to put a lot of sound dispersing materials behind the speakers -- open shelving with lots of books that are randomly pulled forward or backward to create additional diffusion.
My unique problem was that my three other walls are nothing but glass, floor to ceiling (but they can be opened so I can also effectively have no side or rear walls at all). That made for a lot more compromises and careful construction plus window coverings...

sd- So you did put in a false floor of wood over your concrete floor?? Others have advised against that. What do you think you gained on doing that?
Thanks!
Jim
I ended up leaving the concrete, but covered in stone tile around the edge of the room. That tile matches the outside so when the glass is open there is a seamless transition. But then I put a wood floor covered by carpet in the center both to deaden the sound and to provide a more comfortable surface (but using 8 inch laminated studs under the floor). You can sort of see it in this picture (showing the rear and side channel Maggies):
