I was very leary when my wife suggested putting it up there(on its own factory pedistal). Well I said I would try it up there thinking our even our necks would hurt looking up at it from the couch(we are both 6' tall). Turns out that it works just fine at that height. Now that I am finally mounting it w/ in wall speakers etc. I have bought 3 of the yahama NS-IW760's that will be for R, L & Center. The center channel is what I am concerned about. The speakers are about 8" tall & I was planning on putting it below the tv & on top of the mantle. The problem is, that would raise the tv another 7" which doesn't sound like much but it looks scary high. As always, any suggestions welcome!
There are 2 things for you to consider regarding your center speaker's height:
1.) How high is it relative to the height of the TV?
2.) How high is it relative to the L/R speakers?
If I understand correctly, since your TV is already mounted high, the center speaker will be high, yes, but it will be just above the TV, correct? If this is the case, then the speaker's location, at least in relation to the TV, will be OK.
Now, will your in-walls straddle the TV? If so, then, basically, your entire setup, speakers and TV, will simply all be a bit on the high side. Optimal? Maybe not. We all usually have to make certain compromises. But the relative height of the speakers to the TV and the center speaker to the L/R speaker will be OK.
If your TV and L/R speakers were 3' high, but your center speaker was at 8', then this would be a concern. But as long as everything is at a similar relative height, you should be OK. If your center ends up really close to the ceiling, you may have some issues.
As best as I can tell, in looking at the pictures of your speakers online, it appears that the tweeter will be equidistant from the top and bottom (when used horizontally) of the speaker. If this is not the case, you may want to mount the speaker in the orientation that places the tweeter closest to the TV.edit: I found a better online pic and, unless Yamaha instructs otherwise, it shouldn't matter which way you mount the center speaker. If the swivel mechanism is directional, and all the speakers will be above ear level, then mount all the speakers in the orientation that will allow you to tilt the tweeter, as best as possible, downward toward the plane of your ears.
