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.

Max Townshend video demonstrating speaker isolation, AND it’s on a cement floor! Hel-loo!!  🤗

Marvellous convincing video....I have a small before taste with my "imperfect" but effective method to couple- decouple homemade...On the bass and imaging results are speaking... My method of coupling-decoupling is not on par with these Townshend isolation pod but cost me 100 bucks compared to 1700 bucks... :)


Having the money I will buy one for refining results with non perceptible vibrations....Even coupling-decoupling homemade methods gives some results... I use sandwiched between each other 5 different properties materials...Imperfect yes, good yes....

In my experience these seismic vibrations(under perceptible level) greatly affect the sound like ANYTHING linked to the electrical grid or acoustical field of the room way more than an upgrade of gear in most cases...


Most people are unable to imagine these S.Q. amazing transformation when we work on the controlling aspects of these embeddings, be it mechanical like in the Townshend example, or electrical, or acoustical; called all that "snake oil or placebos", like men of the past were calling "gods" strange visitors from the sky...Man need to understand and the simple way is to give a name: god or placebos,or snake oil etc... It is way more simple to name it than to try it with experiment...    :)


This is one of the thing underestimated by us all....



Sorry to disappoint but unless you are isolating with spring type devices you’re not blocking seismic vibrations. The very low frequency seismic type vibrations 0 to 20 Hz can ONLY be blocked or attenuated by decoupling - mass-on-spring isolation. I apologize for having to be the one to tell you. 😢 Your isolation club credit card has been declined. - Regards, the management.

Nothing to be sorry...


If you would have read my post you would have read the word: imperfect, not on par, a before taste, and also my wish to BUY this isolation pod...

I only wanted to gives my impression about the necessity to controls vibrations....

This is very important that’s all...


But I know how you like to own a last word.... then be glad....:)

To your discharge I learn only one thing in my life: it is how to read....I am a man of no gift except that one...And to know how to read implicate to search for the true INTENT of the writer, not only the translation of letters in sound....My intention was to confirm what I learn from this video ...

The funny thing is if you weren’t so “cheap minded” you could have correctly isolated your entire system for what you paid for your homemade devices. Do you see the humor? 😀
