It looks like auto calibration set each speaker to it's audible range. I think that this would work out well, if it sounds good to you. I have mine all set at "Small" which, I think, sets them all to 80 hz. and with a sub covering 20 to 80 hz. It may be that leaving them set at a lower level with a sub, might produce too much bass, which I have experienced.
