I have my 3 rears ceiling mounted and they work well.
I assume you want ceiling mount since your veiwing seat is up against a wall?

The other option is to use 3 x small wall mount rear wireless speakers.
...which all leads me to the following that I have for sale for $399...and it is brand new...the only other thing you would need to make the rears wireless is a wireless sender (which plugs into the BluRay) and a receiver for the rears (which could sit out of sight)...such a Panasonic kit costs $199 RRP.
So for under $600 you would have a state of the art compact surround sound with BluRay Player and Sub woofer...check it out here...
