In my research i've learned that my HTR may be too small to have rear surround speakers. When the back row leans back in thier seats they will be nearly touching the back wall. So I thought I'll install bipoles closer to the center of the room. I've deceided to go with PSB's for my front and rear speakers, now bipole speakers. Reading PSB's overview it says they are great speakers when you place them BEHIND your center of listening. Now I don't know what do to. Any help always appreciated.
