My projector sits on a shelf that is screwed into shelf brackets which are screwed into the studs on the other side of the rear theater wall in a closet. Having the shelf in the closet behind the theater definately helps to minimize the vibrations and surely is better than having the shelf in the actual theater, but I still get some vibrations going through the shelf which can vibrate the projector a bit. Is there any sort of material I can put on the shelf that will kill/absorb the vibrations to some degree that I can put under the projector feet? Any other methods for minimizing the vibrations?

Instead of the other side of the rear theater wall, consider mounting the brackets to the other side of the closet, i.e., to the other wall not associated with the HT room. Aside from that, there are many such platforms made for the isolation of phono turntables but some get kinda pricey.

INstead of the other side of the rear theater wall, consider mounting the brackets to the other side of the closet, i.e., to the other wall not associated with the HT room. Also, consider a SubDude or Gramma for under the sub.

Thanks for the suggestion Kal. Unfortunately I cant mount mount on the other side of the closet as it is not practical in this situation. The platform is a possibility. Where could I find some options for these?

Also, what is a SubDude/Gramma and what do these do exactly?

Thanks

i know for cars they use dynomat to prevent rattling or vibrations dont know if it will work in your situation.

Remember you CANNOT stop the vibrations that are in the air from the sub ! (otherwise how else would you hear it?) but there is a combination of wideband mechanical filtering which will help:

1) get some dynomat or equivalent from a car audio place.
2) get some heavy felt - like an inch thick from www.thefeltpeople.com ask them for "typewriter felt".

The combination of the mechanical filtering will work wonders and is pretty cheap.

Oh, and I also suggest puttin the entire sub on 2 pieces of the 1" felt, but this is only a luxury, not a necessity.

Where could I find some options for these? Then, I suggest a stand-apart rack/stand inside the closet so that the projector is not directly connected, mechanically, to the main room and its vibrations. In my daughter's system, the projector is mounted on a rigid rack in the closet in the next room with an open/close door over the hole in the wall for the lens.

Made by Auralex. Google them and/or see my column comments at: http://www.stereophile.com/musicintheround/1204mitr/index.html

Try Rubber shelf liner.

Thanks for the suggestions guys. I will give these a shot when I get some time to experiment.
