uh, that EQ looks quite extreme, but ok if that works, and yes if too loud, they are too old.
for movies use crystalizer, it makes dialog a little better, i dunno about games+music, i dont use crystalizer for games and music, hmm i donno seems unnatural and unflowy, u try it, u might like it at first, but u might find urself turning it off one day like me.
oh, and how far is ur subwoofer level on the z5500, just curious along with what looks like 70-80% windows bass levels.
