I will get out the spl meter and see what level I am damaging my ears. And check out the fans. There definitely isn't much space the way they are stacked now, I don't ever listen at that level for more than a cd but it does sound pretty awesome. I have to check if the fronts are set to large. I was experimenting with the setup, the sub is behind my chair and seemed to blend better if the mains/center were set to large but I am not positive that is what I ended up with.
