can bipolar surround speaker on backwall with 5.1

I plan to build a 5.1 Home theater. However, the sidewalls of my living room, one side is window and the other is open space. So, I can't mount the dipolar speakers on the sidewalls. I am thinking to mount a pair of bipolar speakers (PSB imagine S) to the back wall, which is about 4 feet from the back of sofa. Does it work to create a surround evelopement? Or, do I need to change to uni-polar ones?

You can't mount a speaker which radiates both forward and backward on a wall; the back radiation would have nowhere to go and cancel out the forward radiation. In any case you would get no benefit from using bipolar radiators in regard to sound distribution when mounted in this manner. I have heard of them being mounted between rooms so they could radiate equally into each but these were full range speakers.

I don't think they will make most video people happy that way.If they were more like the S5,you might be able to pull it off.If you are right against the back wall,then it may get by.If the wall is extremely wide,it may get you in the field, but I doubt it.Others mat disagree.Link for them.[http://www.psbspeakers.com/products/Imagine/Imagine-S-Surround#product_detail][http://www.psbspeakers.com/products/Image-Series/Image-S5-Surround]

My living room is 19 *12, and the back wall is at 12 side. In that case, is anyway to get a surround evelopement in my case? If bi-pole or di-pole will cancel their backward/forward with my original idea, would a pair of direct radiate speakers work?
