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?

@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?

@djones51, thanks for that point.  I was just about to forget about the Perspectives, since who would know better than Jeff himself.  However, looking at the cubic feet, there is almost twice the amount of space in my room as that of @rlb61.  I was really looking at length x width more than cubic feet.  I would not think that a sub would work with the Perspectives in my small room, so yes, it would be without a sub!  Now more to ponder!
