I don't yet have a 990, but am very seriously considering getting one. I think I have a simple question, but these bass management bugs are so complex, I'm having trouble knowing if my question is simple or not.

If I set my fronts and center to large and my surrounds to small and my sub to LFE, will I be happy with the 990's bass managment?

My criteria for happiness are: 1) movies sound right with the sub doing it's thing on explosions, passing jet planes, exhaling dinosaurs, etc., 2) when I switch to 2-channel stereo to listen to CDs, there is no sub, and 3) I don't have to continually reconfigure anything as I jump between DVDs, 2-channel stereo, 7-channel stereo, ProLogic IIx, etc.

Looking at the bass management matrices, I think I won't encounter any problems. But since I don't know precisely what was wrong with bass management before the upgrade and how things have changed now, I can't tell for sure.

Thanks for the input.
