I am in an apartment, and I'm looking to put something under an 8inch sub to keep it from rattling the surrounding area, too much. Any suggestions? I'm thinking there may be some type of pad or something that might minimize rattling folks below me.

Auralex subdude is the popular one.

Thanks for the quick response! Looks expensive for what it is, but it would give me peace of mind for the neighbors. :-) Perhaps there will be some sound quality improvement as well!

People have gone the DIY sub riser route. By the time you buy everything you need to build one if you don't already have it, might not be a worthwhile savings.

For very little money, you could try putting one or two of these mats under each of your subs.

I have one of the 21" version under each of my subs. It stops them from moving around, but whether they rattle the devil hisself any less - my HT is in the basement, so he'd be the only neighbour below - I can't say for sure. I'll ask him when I get there.

keep in mind that a subdude (or any method of decoupling the sub from the floor) will only help with mechanical vibrations from the sub itself... and fwiw, it does that very well...

it will not help "contain bass" in any way...

+1

To my knowledge, it only limits the transmission of cabinet resonance directly to the floor. So if your sub's shell vibrates a lot, it limits this vibration's contact with the floor. It doesn't meaningfully change the way your apartment sounds to neighbors outside it. You're still going to have to police yourself.

yup... that's what it does...

reported "sound quality" improvements are due to the lack of that vibration creating resonances, etc. "removing noise", so to speak...

Go DIY. All you need are a couple of pieces of those black eastic foam which comes with PC packaging and a piece of wood (MDF). Could get some spray paint for the wood (3-4 bucks).

You could also get those large rubber feet from mcmelectronics. Shipping is some 10 bucks. The rubber feet vary from 60 cents to $1.74 a piece. You only need 4 pieces.

Yeah. If you are in an apt., just keep the volume down :-)

well... it might be interesting to measure... but "perceptions" are hard to measure...

that being said, it does what it says it does... i used one when i had my old paradigm servo v2... it stopped vibrations from transferring to the floor... this was pretty easy to empirically prove...

Sorry, I'm on this measuring kick. Bet there's a good reason your perception was positive....

s'ok, i've been on a years long measuring kick...

and you likely could measure part (maybe all) of what is being perceived if you have sensitive enough equipment (picking up rattles, etc.) with an extensive enough data analysis...

for example, vibrations and rattles can cause the user to sometimes localize the sub... when those clues are removed, the sub localization issue goes away...

and so on...

as noted, in my case, the fact that the subdude was doing it's job (ameliorating the transfer of mechanical vibrations to my floor) was very easy to empirically prove, as i'm on the second floor of a house and have a pine board floor...
