do you have HT-EQ on your receiver?
it's included in my Marantz SR5005 and in the instruction manual they say: "soften the treble range of movie soundtracts..."
Somewhere else i read this is used to compensate for the higher treble level in cinemas as compared to HT;
i haven't tried it, except i do use Audyssey Flat as i found out that the Audyssey setting rolls off some treble, which i found was a little weak in my setup.
like SirQuack said, could also be too strong reflections from the side wall and/or the floor.
hope this helps. :-)
