I've never used AT screens, so I don't have experience here. But just thinking out loud:
1. You'll have to make sure the screen is far enough away from the wall for the speakers.
2. If you have to change speakers, you'll have to remove the PJ screen first.
( I don't think I will be changing speakers any time soon Cost too much to change the front 3. Don't have the loot. Plus, since its a new house, there are a ton of other expenses to consider
3. Since your front L/R speakers are on the sides of the screen anyway, couldn't you place the height speakers above the front L/R speakers? And the Center speaker just below the screen?
Don't like the busy look with them exposed.
