I am thinking to do both Wide and Height speakers. For the height speakers, in addition to being placed as high as possible, I assume they should be placed as close as possible to the recommended elevation of 45 degrees. Obviously, there are compromises that will influence this:
Clearances - So nobody bumps their head on the bottom of the speaker while entering or exiting the room.
Aesthetics - A speaker hanging in the middle of the room may not look that great.
SAF - So nobody gets divorced due to the addition of DSX.
In my situation, I think they would wind up at a 20-25 degree angle from ear height. Would it still work?
