I prefer tilting the speakers back so the tweeter is aimed at seated ear height, thus shorter stands, and a method of tilt, like these referenced above
1. Tilt or Non-Tilting stand. (Non-Tilting stand will not have rear lip on top plate)
2. Choose a size for the top and bottom platforms (up to 10" X 10")
(Top and Bottom Platforms can be the same size or different)
3. Choose a height for your stands.

The tilt, combined with angled toe-in combine to alter the reflections from walls, ceiling, floor (both direct and reflected)
