You can also go to the Stereophile website and look through their archives. You will find several articles that relate to room setup. You can also try the Cardas site there is an area there that discusses room setup as well. Some things to understand first though. The deepest low frequency your room will support is 42.3 Hz. A good starting point for speaker setup is to divide room dimension by thirds. If we assume that you will be placing the speakers on the short wall (firing in the long direction) then put the speaker center of each speaker 3'-8" from the side walls and the face of each speaker 4'-4" from the front wall. Your listening seat should be centered in the room, 4'-4" from the back wall. This setup creates an equilateral triangle between your listening position and the two speakers. This setup creates what many audiophiles refer as the "near-field" listening position. Understand that these positions are a starting point only. From here make small movements in the speaker location until you get the desired effects. Moving the speaker back (toward the front wall) will tend to increase bass, although too far and the bass may become boomy and/or muddy. Moving the speakers toward the sidewall will have a tendancy to make the soundstage wider, but at some point the center image will lose focus. Moving the speakers in the opposite directions will have the opposite effects. You will have to spend some time on speaker placement, but the reward is worth the effort. Tom_nice is exactly correct concerning the room modes. Some of these can be treated with room treatments. Last, the equipment will make some differences so audition carefully. Good Luck, Doug
