Townshend Springs under Speakers

Isolation below speakers works from my experience...but it greatly varies from speaker to speaker and from room to room.

The ultimate goal is for the speaker to be held in space as rigidly in space as possible so that any movement in any of the speakers drivers is not modified but a facsimile of what came from the amplifier.

He may be right about this being the "ultimate" goal. Theoretically, at least. In a perfect world.     

In the world we live in however there is no infinitely immovable anything. Everything however hard and stiff and damped always winds up moving and vibrating. Vibrations being what they are in the world we live in some of them reflect right back to the driver, while the rest causes the whole mass to vibrate in sympathy. Just the way it is, and no amount of theoretical "ultimate goal" gonna change it one bit.  

That is why these things work. Everything vibrates no matter what, and so it turns out to work a whole lot better to let them vibrate but in a way that is isolated from everything else.

in my attempt to not promote a competing product aka shill i didn’t mention Vandersteen partnered a high tech firm making constrained layer compound make a “ bedrock “ granite base that Vandy products couple to via three poinrs. Constrained layer damping converts motion to heat and also greatly reduces reflections back from floor to loudspeaker. 

When you dive deep into Vandersteen you discover what i call the orbit of excellence - they tend to show with ARC, Aesthetix, Basis, Brinkmann, Lyra, HRS Triplaner, Audioquest - sharing the spur for innovation and idea, even patent sharing ( DBS ). Another example is R core power supply transformers….

MC of course misses the point that Vandersteen is hardly just a theoretical guy, listen and measure. I expected no less a low reading comprehension retort.

So the guy who has nothing to sell you call a shill, while holding up as a paragon of impartial virtue a guy you know DOES have something to sell. Then after calling me a shill you have the gall to throw the low reading comprehension retort.    

in my attempt to not promote a competing product 

How about instead of attempting to promote or not promote any product you attempt merely to promote the truth? Why not give that a shot? For a change?

Awwwwww... Bless LoL!
