What you think? Could cotton pads be the cheapest effective speaker isolator?

I just got my first speakers friday and I read about how putting things such as squash balls cut in half under your speakers can improve the speaker sound, by dampening the vibration.

I came across this article that shows cotton is a great absorber of sound. (If I am understanding the article correctly)

https://rucore.libraries.rutgers.edu/rutgers-lib/47260/PDF/1/play/
(The material comparison starts on pg85 of the document or pg95 of the pdf document)

So I took the little cotton pads you can buy at any drug store and made 8 little speaker feet. I used 6 pads for each foot with a little dab of glue in between the layers to keep them from moving around. It cost me less than $5

Anyway besides wanting to share with other poor noobs, I was wondering if someone with fairly expensive isolators could see how they compare...or if they even work. Im sure their not as good as the magnetic floating ones but maybe they are decent for the price :-)

Cotton is a good absorber of sound in the form of air-borne energy mostly because of its porous nature. It's effectiveness as an isolator/absorber of mechanically-applied vibrational energy is not comparable because it must be compressed by the load.

I am skeptical of using it for this purpose.

I built my first hi-fi

I built my first hi-fi speakers in 1974 when I was living in an all-concrete apartment block on the 3rd floor. The speakers were 8 cubic foot, 3/4" plywood, with Philips 15" woofers. Even with very modest listening levels in my apartment I was advised by the caretaker that my bass was plainly audible all the way to the basement! He made me bases for the speakers that were simply screw-on furniture feet and that solved the problem. Just reducing the contact area between the speakers and the floor reduced the audio coupling greatly.
