Alternatively, you can try the RPG Acoustics software package that Audio Advisor is now selling for $ 99. Pretty decent for the task if you have a "cuboid" room, and let's you play around with lots of options. I've used it to set up SF Guaneri's in my small (12X14) room. Mind you, you'll still have to tweak by ear, but it does help you rule out the worst positions.
