Thanks for the response. I am doing a 7.1.4, maybe 7.2.4. Regardless of 5.1 or 7.1, I still need a speaker, just more or less of them. I had looked at Klipsch, the RP-140SA or RP-14S. They are a little taller than I was hoping for, at 7.25". Also I'm not sure that they can be ceiling mounted, but it's the height I'm concerned about.
