Dynamic Volume rather more "normalizes" the sound as in addition to compressing the louder explosions it will also boost the lower dialogue as beat1 experienced.
Also, for the OP, you can adjust the center speaker volume to suit your preference as it will not effect the EQ settings. Also note, that Audyssey Dyn EQ will boost the bass/surround audio at volume levels below reference (ie. 0db/80) which will sometimes overpower the center channel dialogue for TV/music listening. The bass boost can be reduced by setting the "Reference Level Offset" from 0db to 10db.
