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.

my experience soft vs rigid is similar to the video.  the best sound achieved on my carpet over concrete floor is when the spikes pierce the carpet and make contact with the solid floor, speakers and subwoofer.

I don't believe that demonstrating the reduction of acceleration of a speaker enclosure proves that it will improve the sound.  
First we have no indication of the amplitude of the vibration and acceleration.  It could be inconsequential. 
Second we have no evidence to suggest that the amplitude of the acceleration is audible.  The enclosure may already be sufficiently damped and braced as to make the vibration inaudible.  
Third is that the reduction of audible enclosure panel acceleation (if any) may make the sound quality less pleasing overall, especially if the manufacturer has tuned the resonance to augment the overall frequency response of the speaker.  Reducing that may make the speaker sound thin and less balanced.  
There is a lot more to this than showing a display of zero acceleration.
