Just wanna see if there's any benefit in utilizing both surround pairs or not in my situation.
Having your primary listening position against a back wall is a challenge. Not just for surrounds, but especially for a flat low frequency response.
Since you have both it wont hurt to try, but I'd be very skeptical that you will enjoy running a 7.1 with both so close to you.
I do not run atmos as 90% of my listening is for music, but I did run 5.1 and 7.1 for a while. When running 7 channels, I had PM1000's as side surrounds and PM800's for rears. In my case I had to mount the PM800's high and at uneven distances behind me. After much experimentation, I determined the 6/7 channels were not adding much. So I sold them and "downgraded" back to 5.1. I do not feel I'm missing anything on the occasions I do watch a movie with a dynamic sound track.
Of course I am missing a bunch, but I was not getting it with the added rear channels due to my space circumstances anyhow. So I didn't, and still don't, know what I was missing. Ignorance is bliss at times.
It sounds to me like you might be in a similar situation given your constraints. I'm actually considering removing my PM1000's as rears and going 3.1 because the rears have to be on stands, very nearfield, on each side of the couch. Consequently, the sweet spot is very small and sitting on either end of the couch is too close to one speaker or the other. This could be an ideal case for BP surrounds. At least some others have suggested this would be a good application of them. I don't know from personal experience, but while I would like to try some BP surrounds, I'm just as apt to sell the PM1000's and dial back further to 3.1.
Given my set up, there is little drop off from 5.1 to 3.1 with the experimentation I've done. YMMV of course.
In your situation, I'd be more concerned about the low frequencies having nulls due to the couch on the back wall. Can you move it forward a foot or two?
