Thanks - been leaning towards the premium ones - but not sure how I want to mount them - may build small custom shelf if I can't find a good bracket to mount to the wall

So I have a dedicated media room that is about 10.5 ft x 18ft that is prewired for 5.1. I'm debating between the RP and reference series. Ceilings are about 9 feet with the speaker plates on the slated portion of trey ceiling. I'm worried RP would be too big for this space as my wife would prefer speakers don't stick out too much but I also want to make sure we have good sound I have a Polk sub 505 to go with it Also - any recommendations of a way to mount front and center speakers? If I get the surrounds I know they have a mount hole for them but not sure how to mount front and center Thanks
