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.

I run 2 SVS SB16Ultras and 2 SVS PB13Ultras. All are on the SVS isolation feet. Theater is on the second floor so I'm not on concrete but I did not lose any low end and as mentioned before the sound tightened up. Not to mention I run these subs at a gain of -24 and can still rattle light fixtures, doors, etc.... if wanted. With SVS typically if you lose some bass you have plenty of gain headroom.

I also have the Townshend platforms under Focal Utopia Maestro towers. I have no idea how the springs in these things are engineered but they are game changers.
