Since we do not have a subwoofer, I am running the main speakers as Large. Today, I was watching Star Wars: Episode II - Attack of the Clones and during the first scene where the huge ship flies over and woofers on my RF-7s were moving like crazy. I had it VERY loud but there was no distortion, no clipping, nothing. But it was just scary watching them move that much. Is this okay or should I reduce the volume?
