Hi I just received my new axioms, and I am wondering do most people leave the speaker grilles on or off. Is there a difference? New to the home theater world, aside from HT in a box. Ended up going with M60 fronts, VP150 center, EP500, and four QS8. I will be using for mainly blue ray, satellite tv, and video games, if that makes a difference for grille or no grill.
