Hello dhorst,
At least one Axiom customer bought extra-long rubber feet at Radio Shack to mount on the bottom of his QS4s so he could place them on shelves. Another customer used some old speaker stands with platforms and used the longer feet to raise the bottom woofer an inch or so off the surface below. Both report excellent performance.
It's not ideal, and frankly, I've never tried it, but it seems to work fine.
Have you thought of mounting the QS4s on the side walls where they are supposed to go anyway? That's the way movies are mixed--with dipole/bipole surrounds on the side walls.
Regards,
