I knew someone who insisted on doing a 7.1 set-up even though his seating was a couple of feet from the back wall. Might as well have done a 5.1 set-up because you couldn't tell the sides from the rears.
For my 2 row HT I went with Paradigm ADP-390's on the back wall, not monopoles, for exact reason you post above.
Ears about 22 inches from rear wall when seated.
(in Paradigm speak ADP = adaptive diploes)
I can tell the sides from the rears, however I have more seperation than DAlba.
DAlba - your polk LSiM702F/X seem very similiar to my ADP-390's.
- you already own them or buying soon?
Can you temp mount on wall with wire and listen to see if worthwhile to run wire in the walls at your 7.1 location?
Most likely 5.1 will suffice and 7.1 may "get lost", but its your time and money as a hobby, it's one of those things that if you don't try it possibly will always be on your mind, keep you up at night wondering if you are "missing" something....
