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.

No. The (appropriate) springs have very high lateral stability for subwoofers, as we say in the trade. Stiffness to any civilians out there. No wobbling.

geoffkait, I understand that. But if you have a sealed sub on a slab, wouldn’t the "wobblyness" be counteractive to the woofer?

Yes. Exactly.

One thing you need to understand, you are taking advice from a self-proclaimed theoretical physicist, who designs interstellar rocket propulsion thrusters in his spare time and has a website devoted to flying saucers. His most impressive accomplishment is consistency: 21k posts, and not a one of them worth reading. Irrelevance on such a scale is remarkable even among audiophiles.

Ok the SVS  are not springs. They're little malleable pieces of rubber with zero engineering thought included.  There certainly is back and forth.

These are not isoacoustics feet.

I would post a link to his website, but every time I do he has it removed. He likes to mislead and insult, but never inform, and at the same time loves to sell the unsuspecting who stumble onto his flying saucer website. So you will have to search him out and find machina dynamica on your own. Then ask yourself how much time and effort you want to put into pursuing the advice of such a one.

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