In a thread that appears to have been removed, a certain poster with a name that insinuates nourishing, mentioned that in-ceiling speakers were of no value because they are too high and the surround effects were not meant to come from that direction. That got me thinking. Perhaps I watch the wrong kind of movies, but it seems to me that MOST of the sound that comes out of my surrounds(which are the fantastic Triad in -ceiling Bronzes) SHOULD be coming from above me. Rain, artillery fire, sniper fire, meteors, spacecraft, airplane flyovers, restaurant ambiance, stadiums, crowds cheering, etc. As a matter of fact, most surround effects would sound odd at ear level. That dragon circling above my head in Dragon heart would be a great example. It brings great joy to my home-theater heart to see my kids and my guests looking up to the ceiling in Master and Commander when the footsteps are going back and forth on the deck above the cannons. It could not be more realistic if the sailors were in my house on the second floor. The bottom line, I disagree with that poster's comment!
