Biggest audio hoaxes

It's called a dedicated audio room. You don't have one?

@bdp24 Are the Townshend products very helpful even for those of us with concrete floors covered with a short rug? My floor feels very stable, and while I respect the idea of vibration control enough to try it, I wonder if my rig is very susceptible to the kinds of vibrations these products help to mitigate?

Concrete is just as "susceptible" as you put it. Yes even slab concrete poured on the ground. I lived in a basement like that, it was very easy to feel vibrations from one person in one room coming through the floor right under the wall into my room. If I can feel and hear it then for sure it affects the sound when amplified a hundred times.

Think of the old-times movie trick of the train robber putting his ear to the track. This works because sound travels through even something as solid as 6" thick solid steel. 

You play your speaker, it sets the concrete to vibrate, it rings, and yes it settles down very fast but for that small fraction of a second until it does it is smearing fine detail. Here, watch https://youtu.be/BOPXJDdwtk4?t=120 Solid concrete floor. See?

The speaker is going to move on its own due to mechanical force of the drivers if not opposed dual mounting. Locking into the concrete will reduce that movement. Thanks for posting another hoax.

Anything with quantum, fractal, or hysteresis in its name.

@millercarbon thanks for the explanation.
