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.

Though 3 points do indeed define a plane, springs don’t care about that. They are more concerned with mass stabilization. I have found 4 springs to in general be much more stable than 3.

Yep @mahgister, the video you provided a link to (I really gotta learn how to do that ;-) is the one to which I was above referring.

Actually Geoff, the video to which I’m referring is a different one. It is entitled "The effect of ground vibration on audio systems", and was taped in a private space (maybe at the Townshend facilities?). It starts with Max discussing the problem, then moving on to possible solutions.

He is shown standing behind a table (and in front of a projector screen, used in his presentation), on top of which he demonstrates different forms of "mass on spring" isolation. He demonstrates the differences between spikes, a plain spring, and his Seismic Pod (which contains the same spring). He covers the issue of the undamped movement of the plain spring vs. the damped behaviour of the Pod.

@pmg1223, in one of the Townshend Audio YouTube videos, Max explains the design and demonstrates the effectiveness of his Seismic isolator. Just do a search for the company name on YouTube, and all the videos will be made available for viewing.

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.
