those of you with projection screens

Do you have problems with the bass flexing the screen? or shaking the projector? I have both so when the bass hits hard the image jumps up and down about 1 inch //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif I tried bolting the screen with more screws but same problem.

Seems like noone has a cure.

As mentioned already, do some projector mechanical decoupling experiments.

Try something simple, two pieces of wood seperated with four corner springs.

Celing

plywood square #1

four corner springs, Maybe 1" - 2" long

plywood square #2

projector

This pic below is too complicated to show what I mean, but you can see the springs

with wing nuts that will loosen or tighten the two pieces of wood [or plastic] making it

more rigid or not.

You are on your own on this one.

With great bass comes great responsibility ... hehe
