That's a good question. I have a pair of SuperSat 50c's and they are mounted horizontally for my front height speakers (the 50's would not fit for this application). The rest are all 50's set up vertically (surround side and backs and wides).
Not sure how the 50c's would sound set up vertically. Might not be so crucial as they are for surrounds, put I am no expert. Might just have to test them both ways and see if it works out in your room. That's the fun part about this hobby, experimenting
The other thing I did was buy two pairs of the Def Tech ProMount 80's. On each of my (not the wides or heights) surround side and surround back 50s, I used only one mount for each speaker at hang from the top. This let my surrounds point down at the main listening position only by 2". This effect gave a phantom over-head sound then when I had mounted the surrounds (side and backs) flat up agains the wall. Like when plane, helicopters, missiles, bullets, rain, people walking over head. Adding the two inch tilt did not take anything away from the diffused effect you get from surrounds. In other words the sounds were not localized but diffused as they should be.
What height for each surround speaker you ask? The tweeter is right at my ear level when I am standing next to each speaker and I am 6' 1".
Also with the Def Tech ProMount's I am able to toe in the surround backs to aim at the main listening position.
Hope this is helpful

Also, how would I setup my AVR to use just on SS50C for rear?
