Sub rattles screen frame

[mcwilson]

I have a minor issue that I'd like to tweak if possible...

I have the standard black aluminum frame for my 110" Da-Lite screen. The screen is mounted on the wall kit that came from Da-Lite. When I watch a movie and the sub is pushed - like the depth charge scene in U-571 - the screen rattles. Significantly...

Any suggestions on ways to dampen the vibrations??

Thanks,

Mark

Hi
Are you sure it is comming form the screen frame? The frame should be snug against the back wall when mounted correctly.If it is comming from the screen you can try using rope calk.

Rope calk is available at Home Depot.A 15' roll is about $3 Tear small
peices of the rope calk off the roll roll it up in your hand to make a ball
Make several balls then place them in various locations on the back of the frame.Re install the screen and press against the frame so the ball of rope calk makes contact with the wall and squishes out.

This will isolate vibration from the wall transmitted to the frame.Be carfull
when working around your screen material.You can use rope calk for isolating rattles,keeping pictures straight and securing bookshelf speaker to there stands Its also good for loading the back of a horn lense on horn speakers
not a bad product to have around the HT for $3

Happy Listening

Thanks for the reply!

I am sure its the frame. I've rewound scenes and walked right up to the screen to be sure. I've also got some sconces that rattle a little at certain times. They're halogen and can get hot. How does rope caulk tolerate heat?

Thanks again for the help.
