I was under the impression that slightly higher than ear level was the best option. Please enlighten me.
A couple of feet above ear level is recommended and probably a good choice if you have to make a decision on pre-wiring, but whenever possible I really recommend experimenting a little with placement if you have the time/ability.
Based on what you just said I would go with wall mounting all of them (I think they sound better when wall mounted) 2-3 feet above ear height. Especially if the side space on the right is tight then I would want to use the most of it by wall mounting.
