Response 2 made a couple of pretty good points, but I'll amplify a little bit: * Try some different positions with respect to the back wall - experiment by moving it closer and further away, you'll be able to hear what position you prefer * Remember that side walls contribute just as much to loose bass performance as the back wall, so try to be a couple of feet into the room on each side * I generally start with a more  or less equilateral triangle with the speakers and listening position, but by all means experiment.  Trust your ears. * For a much more complete treatment of speaker placement, you might take a look at http://www.gcaudio.com/resources/howtos/speakerplacement.html I hope this helps and hope you enjoy your new gear!
