Although this is against the conventional wisdom for speaker placement, ...I don't think it really matters for Omnisats. That's why Mirage said you could put them anywhere, either on the walls or the ceiling. Omnisats are designed to radiate in all directions so a specific placement isn't as critical. I heard some Omnisats at a Mirage dealer not too long ago. The ones I listened to were on stands. As I stood up and sat down, and as I walked 360 degrees around them, I was amazed at how consistent the sound was. You might experiment a bit with placement in case your room has peculiar acoustic properties, but other than that, I think you have a lot of flexibility with this type of speaker regarding placement.
