My first thought on your seating possition (2' from back) and monopoles mounted on that same back wall, is that you're compounding your "boomy", "peaky", "low fidelity" bass problems!!! This won't sound very good. Infact, you can forget any audiophile refined applications here, or even good "midfi" sound from this setup! You and your speakers are then located in the most bass heavy/peaky spot in the room!...not the way to do it.
I would go for dipoles on that back wall if you must, because they'd likely be much better balanced to be on the back wall vs. monopoles(which more often than not are better balanced out in the room more!) (if you doubt, just measure and find out with test tones/sound meter).
Also, dipoles are more diffuse sounding mostly, which lends to a much less specific and distracting experience back there. You get lost in the movie much better, and they're less intrussive.
If you gotta go monopoles, they're trickier to make dissapear if you ask me.
