Michael, you might possibly reach over and do sub settings by "braille" as I do after backing my EP500 tightly into a corner. Because of the sensitivity of my fingers, I've determined that the level setting I arrived at(with the receiver sub trim at +2dB)was about 7:38:23. Don't overlook the significance of the trim control which Peter mentions, especially if your room isn't very large. In my particular combination of room size and sub location in a corner, I found that the "full" trim setting gave smooth yet still very strong results in combination with my M22s.
