I have had my Yamaha HTR-5930 HTIB for about six months or so, but I have never calibrated it. I mean, I've put in the basic information, like that I have a subwoofer, how many speakers, and such, and I've turned the center channel up by 2 db, but as far as the other stuff goes, I'm not too sure on how to proceed with speaker distance, LFE level and other adjustments. The setup is in my bedroom, which is reasonably small, about 11.5'x11.5'. I am getting ready to buy a HD DVD player, so I want to be sure my speakers are performing at their optimum ability. Is there a disk for audio calibration that I should purchase? I know they have calibration disks for video, but I don't know if they do for audio. Anyone who can help me out on the steps I should take to properly calibrate my system, I'd very much appreciate.
