Anyone have the Klipsch RP-500M bookshelf speakers?

I am starting to piece together my 5.1 surround sound system, but we are looking for a new house and am not sure how big the new “theater” room will be. So I am putting together the set up in reverse and am buying the back speakers now to use as the front channel speakers in the current house because it is a smaller room. Does anyone have the Rp-500M speakers as front channel speakers or rear channel speakers? If so, how do they sound?
