We don't know all the details of your planned theater setup.
Will you have just one row of seating, or will you have a second row behind the first row?
Regardless, a good rule of thumb when it comes to screen height position is this:
Position your seat exactly where you would like it to be. Now sit in it exactly as though you were going to watch a movie. If it is a straight backed chair, you will likely be looking almost perfectly straight ahead. But if it is a recliner, your eyes will be looking up at an angle.
Basically, what you want to do is imagine a perfectly straight line shooting out of your eyes when they are in a perfectly neutral position. You can actually use a laser pointer and line it up with your line of sight to see exactly where that imaginary line would fall on the all in front of you.
With that point now located, the ideal tip top of the screen should be no more than 17 degrees above that point. THX recommends that the top of the screen be no more than 15 degrees above this point.
Check out the
THX diagram here for an illustration of what I am talking about.
The THX diagram shows a line of sight perfectly parallel to the floor, but if you are in a recliner, the line won't be parallel to the floor like that. It'll be angled upwards, so just keep that in mind
So basically, if your seat is a recliner and you always (or almost always) watch in a reclined position, having the screen up higher on the wall won't be a problem and may actually be preferable. But it really depends, so it's very much worth your time to figure it out, measure it out and make sure in the planning stage before you go buying anything.
Some other potential solutions:
- an acoustically transparent screen is certainly a great choice! An added benefit is that you can get ideal center channel speaker placement this way and you can also use 3 completely identical speakers across the front
- another solution would be to use horizontally oriented speakers for all 3 front speakers. Some speakers are well designed to sound virtually identical whether positioned vertically or horizontally. Some examples are Ascend Acoustics Sierra-1 speakers (ie. you would simply use 3 of the Sierra-1 Center speakers across the front) or the Emotiva speakers are all designed to sound virtually identical whether placed horizontally or vertically.
Regardless of how you solve your issue, avoid placing the front L/R speakers in the corners or very close to the side walls. IMO, it just isn't worth destroying your sound quality in order to accommodate the screen. That's robbing Peter to pay Paul as they say
Best of luck!
