Well I finally got some time to tinker with all those settings and suggestions you made. I really can't tell if anything changed.
Here's what I know. I uninstalled and inspected the surround speakers. The connections are solid and I confirmed in ALL Channel music mode that the tweeters are working. So unfortunately that theory is dead.
I then switched the speakers back and forth between dipole and bipole mode (there's a switch on the speaker). Based on the naked ear it did sound like Bipole sounded better. I also discovered that there is a Dipole/Direct speaker setting within the AVM Speaker configuration menu. I did have the setting correctly set to Dipole but I decided to play around and found that when it's set to "Direct", the Dipole speaker mode sounded better than dipole/dipole .
So I spent 3 hours listening to (speaker setting/AVM configuration setting) Dipole/Dipole, Dipole/Direct, Bipole/Dipole and Bipole/Direct. I "think" Bipole/Direct sounded the best. Hell who knows after watching the Dark Knight 10 times in a row listening for the smallest variances. Now I know what it would have been like to be Howard Hughes. I was about to go NUTS.
So after reading the speaker manual 100x and playing with all the settings I decided to run two additional ARC tests in two new configuration modes.
I already had ARC graphs in (Speaker Setting/AVM Speaker Config Setting) in Dipole/Dipole mode. The next two tests were Dipole/Direct and Bipole/Direct. My charts are below. Once again I have NO idea if anything improved. I feel like an idiot. I wish I could tell. Is my tweeter problem still there?
I'd really appreciate your analysis. This surround issue has me all tweaked out. The good news is I did take your advice and I'm ordering a new "deeper" sub. I agree...we can do better. Now I need to resolve the surround problem.
Lastly if you could educate me on a few new questions, I'd REALLY appreciate it. You've been SOOOO helpful!
Do the Direct versus Dipole configuration settings in the AVM make a big difference. I assume I'm supposed to match my speaker to the speaker configuration setting; i.e. dipole speakers get matched to the dipole setting.
Does the Bass and Treble setting make any difference here? Do those settings effect ARC or are they turned off? If on, what do you keep your treble and bass set to?
What's your favorite Anthem movie mode? Anthem Movie or Dolby P2x?
Thanks for ALL the help!!!!!!!!!!!!!!!!!!!!!!!!!!

As the Manual states, the Dipole setting merely simplifies distance (timing) adjustment for dipole spears -- i.e., matches the largest distance for your other speakers. Since dipole speakers work by bouncing sound off the surroundings, their direct line distance from the listening position is not relevant.
In any event, if you have the surround speakers themselves set to Bipole you should use the Direct setting in the Anthem so that the speaker distance (timing adjustments) are properly applied by the Anthem. If you set the speakers to Dipole, use the Dipole setting in the Anthem.
----------------------------------------------
You didn't mention this time what you were using for the Max EQ Frequency target when you did the ARC calculation. I think you should probably try raising that from the default 5KHz value to something closer to the max 20KHz value and see what sort of results curves you get.
You can try a few different values up there quite easily to see how the Calculated (green) curves change. Do this with both the Bipole/Direct and with the Dipole/Dipole Measurement files. Discard the Dipole/Direct Measurement file as you do not want to use that configuration.
It may just be that your surround speakers are weak in high frequencies, but if you tell ARC to correct up that high that should help.
-------------------------------------------------------
Bass and Treble are "on the fly" adjustment controls you can make for your personal preference according to whatever content you are watching at the moment. Their settings do not affect the ARC setup. In the 2+ years I've had my D2 I don't think I've ever used them.
I listen mostly to movies with multi-channel tracks, and I have a 5.1 speaker system, so there are no choices for me to make on surround audio modes -- i.e., there's no work for the D2 to do. 5.1 in just goes to 5.1 out.
Since you have a 7.1 speaker system, I suggest you use PLIIx to raise 5.1 channel input to 7.1 speaker output. It's entirely personal preference which of the PLIIx modes you use to do that -- read the Manual for some discussion of the differences between them.
When listening to stereo content, my personal preference is:
1) For Music stereo content: Stereo -- i.e., no surround speakers. Just the LF/RF and sub.
2) For regular TV programs: Anthem Cinema
3) For Movies with stereo sound tracks (on disc or broadcast TV): PLIIx, to raise the 2.0 channel input to 5.1 speaker output. Note that I don't have to chose between the different PLIIx modes as they only differ in what they would send to rear speakers and I don't have rear speakers.
I used to add THX post processing when watching movies, but now with ARC I don't do that any longer.
