Hey Bt - I have a plasma TV. I put the center speaker below by building a shelf for the TV. It works great. You can see a picture of my setup in this forum.
Look for the Thread "More reviews of VT-12" started by Grayson73. The picture was posted on Feb 10.
The stand is secured to the TV stand and the TV is then secured to the new stand. The center speaker sits inside the new stand.
Hope this helps,
Perhaps this link will work...
