Bill yes I got the rp450ca, rp240's, rp150m's, and the atmos rp140's. The atmos speakers set on top of the H3's ( so they are only two foot off the ground) but I think I want to hang them on the wall pointing down. Seems like that would give me some height to the sound image. I don't want to cut a hole in the cileing so I was thinking about a g16 low profile mounted in the top corner/ middle firing down also for a fuller height expieience. I think the denon will handle an extra channel. Thoughts anyone?
