Rosedanny,
Be thankful that your speakers have instructions on how to perfectly time align the drivers. Take advantage of it. Time alignment of the drivers is the first parameter you should adjust. After that you can mess with toe, speaker placement, etc. If you mess with speaker placement, you will have to readjust the tilt to get the time alignment right.
You can tweak, but for goodness' sake, make sure the time alignment of the drivers is correct :) I doubt you can improve anything by having the drivers "out of" time alignment.
