Go to a good audio shop and ask them how much they would charge to do the set for your 802's. This absolutely cannot be done through room dimensions alone and advice you get on the 'gon. You need someone who really knows what they are doing to get it right, and they need to be in the room to do it. Literally an inch one direction or another can make a very big difference (I know, I didnt believe it either until I heard it). Depending on your connections and luck, this will cost anywhere from a gift certificate to a nice restaurant to a couple hundred bucks to get done. But even at the high end of cost, it is a bargain. Do it. You've already sunk a lot of money into your speakers, give them a chance to sound their best.
