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.

It’s par for the course to have more bass than is actually on the recording. Hel-loo! But this is not the 1980s, guys, mc apparently thinks it is.

I must wait to sell my house but I cannot wait to experiment with my speakers and add to my sandwich of 5 different materials under them 4 springs and directly under the speakers a bed of quartz sand/ small peebles. The sandwich between them....

I trust the springs to isolate from external vibrations, and for the quartz bed to manage gently internal resonance with the sandwiche… :)

Looks like I dropped a grenade. :)

Let me clarify what I was thinking about driver/cabinet motion.

The combination of small footprint, light weight, and distance from the floor are what make this issue most prominent. If you have smallish stand-mounted monitors I encourage you to try some weight on top and listen. 

Would it happen with a big heavy woofer, inches from the floor? Probably not nearly as much, but I certainly don't want it spring loaded to the floor any more than necessary.

My speakers actually were loaded with 70 pounds on each, and this was good... I will try someday juste the springs compared to the speakers loaded with weigh on my sandwiches....The weigh gives some damping, and the different densities materials I use give some coupling-decoupling but also some tuning.... I will compare someday with the springs with a bed of quartz....
