Hello W. Did you ever get a clear answer to your question? I have not been able to get clarity on this. I am also interested in getting the 500sa’s but may have to hang them as front height speakers. Do you put switch in “atmos” position or “surround”? I only want them to experience atmos effects. If hanging them as opposed to up-firing on top of my tower klipsch speakers loses ability for atmos then im not as interested. Thank you.
S.
