This differential is done intentionally, that way the sound effects are much more dramatic. Next time you are in a theater pay attention to the dialog and you will notice how low the volume is compared to the effects on the ST. Some new HT receivers have a normalize feature so that when you want to play a movie say late at night and do not want to have to reach for the remote al the time to turn the volume up and down throughout the movie you can normalize the levels and play one setting. It is amazing how mush you loose the effect when you play a movie this way.
