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

@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!

""Mine are about 2 feet off the wall with 2’x4’ 2inch thick absorption panels behind.""
This was the exact setup I had with my Perspectives when I had them. Worked very well. However, the Pulsar is a little monster, and may even satisfy you without subs. A friend of mine has the Pulsar 2 Graphene's. I can't believe how amazing those are. Big, rich, deep bass. Just incredible.

I suggest that you give Jeff Joseph a call at (800) 474-4434 to get his opinion. Jeff is a great guy and, since he designed the speakers, there's probably nobody better qualified than him to give you the lowdown for your situation.

A little off topic but how do you like the HP / Pulsar combination.  I have a new pair of Perspectives (original) sitting at my dealer while I sell my house and move.  I also have an HP w/ KT-150's.  Just wondering your experience with your combination. 

Not only is your room on the smaller side, it’s square, which is usually a nightmare for bass issues. With a room that size and shape I think the flexibility of placement and fine tuning capabilities of a sub with the Pulsars would be a much better solution. Plus with a sub you’ll be able to get down to an honest 20Hz that will add to the music in a way the Perspectives alone cannot. I’d also assume adding a good sub (or even two) could well cost thousands less than upgrading to Perspectives. If it’s me, I’d get a pair of SVS SB2000 Pro subs for $1500 (with a 45-day, risk-free return policy) and see where they bring you with the Pulsars. My experience with good and properly set up subs is that once you hear all they add to your system’s overall performance you won’t want to listen without them anymore. Just my $0.02, and best of luck in whatever you decide.
