Joseph Audio Pulsars with REL Sub or Perspectives in 11x11 Room?

Thanks for your input! My room is not a good room acoustically.  It is all reflective walls and ceiling (carpeting on the floor though), and I have one spot for putting my "listening chair." It is a converted bedroom, so it is not open at all. The Pulsars with the sub definitely pump out a lot of bass, and I have already spoken with GIK Acoustics about treatments for the room to make it a little more friendly.  But I wonder if, overall, there will be a sizable difference in Treble and mid if I go up to the Perspectives from the Pulsars.

What would you guys say is the standout difference between the Pulsars+ sub and the Perspectives?

Never heard the Pulsars but I would think coherence. I don't have an ideal room either. I have done what treatments I could then got an Anthem STR using room correction which Softened the bass is the most noticeable improvement, I am not a fan of boomy bass. 

@prof, you mention having the Perspectives "well off the walls."  I am pretty limited to placing them about 2 ft. max off the walls, which puts me about 8 feet from them, max.  Do they need to be farther away from the walls?

moto man,
My perspectives tend to be about 3 3/4 feet from the back of the speaker to the wall behind them.   Left speaker about 2 feet off the side wall, the other speaker near a room opening.
I haven't played with the speakers much closer to the back wall because I have a bit of an unusual room demands that forbids such placement as permanent (the right speaker is near the room entrance and placing the speaker closer to it's back wall actually puts it in the pathway of entering the room.  In this case this "limitation" works out fine as most speakers work really well in the room at that distance from the  walls.

Mine are about 2 feet off the wall with 2'x4' 2inch thick absorption panels behind.
