Do the subwoofer crawl look for best/loudest bass then do it again and look for the smoothest sounding bass. You then have to decide which you want, really loud or nice and smooth, I would go for smooth. Next jack the sub level up a few db in the receiver from the rest of the system as many of us do and then try a movie and some music and then tweak some more till you have it sounding the way YOU want. BTW, go buy a SPL meter as anytime something gets moved in your room you may find you want to recheck the settings. That SPL meter is now your best friend inspite of what your wife says or does
