Looking at using a receiver to power a set of S2s, if you use a receiver to power your speakers and you are listening to music (stereo or even maybe multi channel), do you normally turn off the room correction feature ?

Also, do you think if it makes any difference whether the grills are on or off ?

What about movie watching, I think RC is probably best kept on for movies, but will the center channel / dialog maybe be cleaner if the grill is removed ?
