Subwoofer Footing - Connect or Isolate?

What is considered the best way to "foot" a subwoofer, should one try to connect it with the floor or isolate it? I have a REL 7i that I have firmly coupled to my wood floor with the weight of a 42 lb curling stone, mainly because it looks cool. Would some sort of isolation be better and reduce resonance from the floor, or could the connection with the floor help "drain" resonance from the subwoofer cabinet?

Another Auralex Subdude user here.  Cleans up muddy bass that obscures midrange detail when flooring is problematic.  Everything is more refined and detailed top to bottom.

Great feedback everyone, thank you. As a low cost test I ordered some Nobsound springs, though something like a Subdude is definitely under consideration. I shall report back.

Has anyone tried the  Auray ISO-SUB Subwoofer Isolation Stabilizer?  Same overall dimensions as the Auralex but made of slightly different materials.

With that sub you will probably only need 3-4 springs per footer. This will leave you with 12-16 springs left over, enough to make another set of footers to use under another component. You can make additional footers from MDF, acrylic or wood. Drill some 1/4" divots the way Nobsound does to hold the springs.

The improvement from under the sub will be okay, not nearly as much as Townshend Pods but at least as good as other stuff mentioned. Combined with using the extra set under a CDP or whatever you will find hard to beat for $30.   

You do not by the way have to put them under the existing factory feet. They can be used just inboard of that, and with a spacer can wind up with almost exactly the same height above the floor as now.
