I need help with speaker set up. Just upgraded my receiver to an Onkyo 606. I would like to add the additional two speakers, but my problem is the set up. I currently have my rear speakers directly behind me with no space, the sitting is right up against the rear wall. All of my current speakers are boston accoustics and I would like to add the OWM3's. Is it required to have spacing between the sitting area and the rears? Would it make sense to add the additional two speakers and get the full affect? Would love to upgrade but placement may be a problem.
