What worked for me: 1. Move front and surround and height if you have them speakers to full range. 2. Set center speaker cutoff a few hz higher than normal, like 80 or 100 3. Turn up level going to sub. Turn down volume knob on the sub. This prevents auto off You get a lot of the low end effects off the sub, and the center and sub is just for dialogue. You get that depth effect without the dialogue being muted. I feel filmmakers do this so their movies don't age. Supposedly they're going to have a laser speaker, and the flat panel tv will be a speaker itself with the sound shot across the screen. All those movies get a new release for that.
