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?

Sorry about being Mr Pedantic, but this always annoys me, like when people say "acks" instead of ask, and "proably" instead of probably.

1>> and 6>> To dampen something is to get it wet, to apply water, to moisten.

To damp something acoustically is to absorb sound energy; heavily damped oscillations die out faster than non-damped oscillations.

Dampening oscillations just makes them soggy, and won't do the electronics any good! ;o)
