DIY speaker isolation base for a wood floor

The video "lost" me, as in lost any respect I had when they started talking about seismic coupling into the speaker impacting micro-detail. The spectrum of background vibrations is predominantly <10Hz, pretty much nothing >100Hz for starters.  Surface area of a speaker maybe 10 square feet? Surface area of room walls, ceiling, floor = 1000 square feet. If those microvibrations are anywhere near audible, it's too late, your room is already a giant speaker for them. If you think the movement in these frequencies and amplitudes of the cabinet impacts the "detail" of the drivers, then your head is going to explode when you think about that mid-woofer trying to play say a 1Khz tone while that mid-woofer is experiencing comparatively large subsonic and sonic motion from your turntable (let alone from the music itself).

Got a good laugh out of claiming the cabinet does not move in one sentence to claiming large floor coupling the next. Which is it?   Could acoustic coupling be a primary mode of coupling to the floor ... after all, where is the energy coupled, to the cabinet or to the air?

In my humble opinion you are wrong regarding the use of Spikes,

You are right, you don't need a muse, you need an inner voice. You seem to be missing one. Sure, when I want to learn about "negative-K" isolation basics, of course I am going to go to 6-moons, the well accepted authority on vibration isolation .... :-)

How about the actual website of the MFR where the system is broken down to show that conceptually it is very simple. The completed system looks complex due to the multi-axis nature of the completed assembly. The basics ... quite simple:

You say yes, I say no. You say stop, I say go. You say hello, I say goodbye.

This is a topic that can be difficult, challenging, and even complicated to understand because it is not always intuitive that is why I have suggested that you acquire a basic, introductory, elementary text on electronics and then work on building you're knowledge, comprehension, and understanding from there and of course there are many experts on this forum who are usually willing to help you.
