I will be acquiring these speakers in a couple of days. Along with a 300wpc Yamaha rig, all free of charge. I'm sure it will all be in pristine condition. What do I absolutely need to know about placement and set-up. I don't know if there will be any literature with the equipment. I have a large 20 x 30ish room with cathedral ceilings. I've done a little reading on the web and I'm starting to get excited about playin' around with the set-up. It will be a stereo only set up at this time.
