I used an Axiom Full Metal Bracket too. It basically mounts to a stud in your wall, and then you connect the other half to the back of your speaker, connect the two up and you can angle the speaker as you need to. It doesn't show up well in newf's image because it is directly behind the speaker itself.
Here is when I had my (now gone) VP150 mounted above my 104" screen that i used to have back in my v2.0 home theater. You can't really see it, but you will notice that there is no shelf or anything. It just makes the speaker look like it is magically floating up there.
This is mounted to the wall:
Prior to that I planned on mounting it to the ceiling, but in the end I wanted as much height as I could get so my screen was able to be a little higher. Here is it mounted from a white Full Metal Bracket hanging from the ceiling before I put it on the wall in the picture above.
