SVS Subwoofer Isolation feet. Will I lose bass?

Most of what I see about subwoofer isolation has to do with minimizing rattles or bothering the neighbors.  But what about a sealed subwoofer on a concrete slab?  Would these dampeners not "dampen" the bass as well?

My setup...  Dual SVS SB16s on a concrete slab.  I don't have a rattle problem and the room is 20ft tall so I can't afford to "lose" bass because of my shakey rubbery feet.  

I've read and seen many great things about these but I have a hunch it would hurt a sealed sub on a slab more than help.

Hey, mc, are you huffing Clorox again? No offense intended.

None taken. To offend calls for standing you don’t have.

Good comeback. Did your mother write that for you?

Isolation feet are not needed here and could be detrimental.

It probably won't hurt you as much as it would smaller speakers.  The idea is that you want the speaker to be rigidly fixed in all three dimensions without rocking.  The woofer's apply a great deal of energy against the cabinet. Even light rocking can reduce the output into the room.

You do want to prevent transmission from the cabinet to the floor, and create a vibration signal that reaches you at a different time than the acoustic one.

Thanks, that's the kind of info I'm looking for.  So basically, leave the factory rubber stubbs on sealed woofers on a slab.
