If you are running just a 5.1 set up do you recommend a set of BPs over the Bs?
Since I don't really have the option to wall mount on both sides the BPs are probably out and I dont have any room to place behind the seating area so can't really go 7.1 I figured I could get Bs for rear in the 5.1 now and then when I upgrade to 7.1 at next location get the BPs to fill in the side?
We've found that the 4BP works very well in either side or rear locations due to its bipole nature. At the sides they're definitely less immersive than the 5DB, but still a nice improvement over the 4B as sides or back surrounds. I'd recommend giving them a shot over the 4Bs first, I'm sure you'll love 'em.
Thanks blkhks! If these are installed 3-4 feet above the listening area should I be concerned with directing them down towards the zone?
Nope, the speaker is designed to be flush mounted. The way the speaker works is by providing a more diffuse sound field that creates an immersive surround effect and you would actually diminish that if the speaker is angled toward your listening position.
