First of all, wall mounting will count out most speakers. You need something designed to be against a wall. That means definitely no rear port. I'd go for a sealed box.
Secondly, mounting up high means that you will have to angle them downward. Awkward to say the least. You will never have good imaging for stereo listening.
Third, mounting the fronts up high creates a really weird phenomenon: you see the picture in front of you but the sound doesn't relate to what you see. ie car crash in front of you but the sound comes from up high some where.
Fourth, high performance is a relative term-do you want loud, efficient, musical or what?
I'd give 3 suggestions here:
If theater is the main choice find a set of Gallo micro's, mount them up high and angle them down. It will fill the room, sound good and won't be affected by the walls.
If Music is more important-Put your center, right and left all very close to the TV. When you are really listening to music, just pull a chair into the sweet spot (if you can find one).
Go buy one of the sound bars like a Boston Acoustics. They sound good, go right under the tv and fill the room. Add a sub if you like.
