I'm looking at using M80s with an 83" screen, with the bottom of the screen about 36" above the floor to fit the needed PJ geometry. The M80 tweeters look to be around 36" above the floor, which is quite a bit below the center of the screen, which is about 60". Will I get significant benefit from raising the M80s about 12-18" off the floor, say with concrete blocks (covered to look good)? They might look pretty tall, but the sonic image should be more in synch with the image. Any thoughts?
