Light fixtures above 18" subs falling apart...

[jpalmer1717]

I am looking for products that I can stick to metal surfaces that will dampen vibration. Something like good ole dynomat but in small quantity and cheaper. I have 18's on each side of a projection screen with really cool light sconces above each sub. They are the only rattle in the room. But I REALLY don't want to get rid of them. Does anyone have suggestions as to a rubber material I could just later the back sides and any metal to metal contact points?

Wow, your subs 'rattle' that much ? what is their couple / de-couple configuration to the floor ?

I've got 4 3" super soft silicone rubber feet under each box. The light fixture is a sconce wall light which are only a few feet above the subs.

How are the sconces attached to the wall? Is there a hollow metal housing attached to the wall? Are there screws into the drywall, or into studs behind the drywall? If the vibrations travel through the wall, those places might be how the sconces pick up vibrations from the subs. But the vibrations could also travel through the air.

I've two ideas for material that might work for you:

• Weather Stripping
  Look in Lowes or Home Depot for weather stripping, like for doors or windows. There should be a variety of rubber or foam rubber strips with a sticky backing on one side. Put it where you can, especially where the sconces are mounted to the wall.
• Modeling Clay (Plasticine)
  Look in a craft store like Michaels.

They are attached to round electrical boxes that are attached to studs. And they have a large hollow rectangle metal box that attaches to the back plate. Lots of metal on metal action. Thanks for the suggestions, much appreciated!

Similar to modeling clay, I've used blu-tac or museum putty to solve rattles.

Get a ceiling fan I’ve never had those disintegrating from my 15” sub . Or those long fluorescent lights.

Ceiling fan and fluorescent lights are two thing nobody should have on the same circuit as audio gear. Both are highly likely to introduce noise in the circuit when they are on.

Audio Advice youtube recommends blu tack. Sounds reasonable to me.

Can you isolate the parts that rattle? Is it the wall box and the light's backside or other parts on the light itself?
