I am using the inexpensive Bentley FS-50's for my Atmos duty as I cannot cut into my ceiling. They sit high up on the sides just below the ceiling (got 4 of them). Sounds good to me and get the effect I was after - More of a bubble of sound around and just be warned not all Atmos tracks are created equal, some use Atmos implementation well and others don't. I Tried Ceiling Bounce Speakers, Don't waste your time with that, never got the any noticeable effect. I think Bizkit sells the Bentleys
