I am installing rear speakers as a part of what is currently a 5.1 system (would like to do 7.1 sometime in the future). And I would appreciate some help determining what is the best position to mount the rear speakers.
The AV system is in a "Great Room" (~25ft ceiling). The TV, front and center speakers are against a floor-to-ceiling wall, what I'll call the "front" of the Great Room.
The rear of the room does not have a floor to ceiling wall however. The rear of the Great Room opens directly into the kitchen.
The kitchen has a 10ft ceiling, then above that 10ft height, it becomes the upper part of the rear wall of the Great Room.
This division (from the rear of the Great Room into the kitchen) is about 3ft behind the main seating area.
So as I see it, I have the option to mount the rear speakers in 2 ways:
1. Wall mount. Rear speakers would be about 11ft high and 3ft behind the listening position.
2. Hanging from ceiling of kitchen. So they would be lower, and could be farther back. Say, 9ft high, and 4ft (or more) behind the listening position.
What are your thoughts? Is one of these arrangements "better" than the other, acoustically speaking?
