Nice pic. Just like it will say in the package when you get the speakers, place them at the front edge of the stands (maybe hanging over by 1 inch/2.5 centimeters) so they will project well and you have room for the rear port. Whether or not it would be worthwhile to move the shelves lower to get the speakers at ear level is entirely up to you, but it would likely improve things a little.
P.S. There seems to be something wrong with your TV. The letters are scrambled or something. I can't read any of it, although the resolution seems OK. :-)
