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.

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

Yep, unless you can feel vibration through the floor itself.

Not so fast...

More  conflicting pseudo science-refer to subwoofer suggestions

Lots of unconventional suggestions that some swear by.

I have the subs on brass footers and maple slabs. Do they really do anything? Any tweaking is best to just try yourself.

Mine just look great because I had them cherry stained to match the subs.

Thousands of audiophiles isolate their speakers and subs with spring-based iso devices. And guess what, they ain’t amateurs. This isn’t the 1980s any more, guys. Wake up and smell the coffee! ☕️

It's been said here perhaps hundreds of time: watch the Townshend Audio YouTube videos wherein Max Townshend demonstrates the effects of installing a set of his Seismic Speaker Podiums between a loudspeaker cabinet and the concrete floor they are sitting on. THEN ask questions.
