Hi Frank - In all of the theatres I've witnessed, I've never seen this condition of screen vibration due to the subs since with the perfed screens, the hole density is high enough and screens tight enough on the frames where I've never seen this condition. Also, some theatres have their subs located below the screen on the floor and behind the curtain valance.
I've seen both and in the theater with the subs behind the curtains the curtains dind't really move either. The subs were however about a foot and a half back from it.

hmmm, thanks, guys. It was just a thought. I figure asking is better than mounting those monsters only to find out my screen is acting like the top of a kettle drum! We have insisted that the subs be at bottom of the screen level so we can get more spl in the bass region out to impact the audience more. Having them 30ft in the air looses that really filling rattling bass presence, eventhough acoustic guys insisted that the low end couples to the room better when they are in the corner. I say, but yah, they are coupling to the ceiling....the people are on the floor! We tried them out on the stage on either side of the screen and even THAT made a huge difference. Floor level they stay.
