I've seen installations with QS4s and QS8s hanging on brackets from the ceiling when there were no side walls available. I've also seen an install with at least 1 QS mounted on to a soffit around ductwork. Just some options. The QS speakers are REALLY fogiving on their installation due to their advanced design.

With all of that said, be sure that you post lots of pictures of the progress. We LOVE pictures...
