Dampening subwoofer vibrations

Hey all...

I'm not sure if this is the right board for this question, but anyway:

I have a rather large sub on my 5.1 setup (Z5500), and I'm worried it's going to piss off whoever's living on the floor below me next year (we have very thin floors). Is there any way that I can still use it at night (at reasonable levels of course), and cause minimal disturbance to a sleeping person below?

Get some nice rubber stoppers to set the woofer on. If you can't find any soft rubber furniture feet, get two packs of cork coasters (for putting drinks on) and put them under the woofer two layers thick to keep it off the floor.

This should virtually eliminate rattling caused by the woofer moving around on the floor, especially if you have a hardwood floor.

Alternately, you could put it on a pillow or cushion.

Of course, these suggestions are COMMON SENSE and if you can't figure something like this out on your own you should be contemplating suicide.
