speaker/stand, couple or isolate?


I've read a lot about floor standing speaker interaction with the floor and whether or not isolation or coupling might be the right approach depending on the type of floor, e.g., concrete, suspending wood floor, etc. I suspect the same rules apply to the speaker and the stand as a unit but what is the common wisdom about how should standmount speakers be placed on the stand, especially the larger/heavier speakers on 4 leg sand/rice filled heavy stands where tip over is not much of a concern. Thanks.

In years gone by, Tekna Sonic dampers for speaker cabinets and subwoofers effectively dissipated cabinet vibrations - with no side effects. Sadly they went belly up πŸ”many years ago. The good gnus πŸ‚ πŸ‚ is that isolating speakers accomplishes the same thing, dissipating cabinet resonances, plus prevents any hint of mechanical feedback πŸ”™ to the front end electronics. The only good cabinet resonance is a dead resonance ☠️ Speakers are not (rpt not) the same thing as musical instruments. 😬
Isolation of speakers eliminates the variable of what kind of floor it is. If thy eye πŸ‘ offend thee pluck it out! It could be a trampoline floor, it could be a cement floor, it could be a suspended floor on the tenth floor. And higher floors are moving side to side πŸ”› due to wind and other forces - and in rotational directions πŸ”„ as well as vertical. People tend to hyper-focus on vibration in the vertical direction πŸ”only. There are six (count em!) directions, at least. In the horizontal plane there is an infinite number. πŸ™€
You would be light years ahead using bungee cords to suspend the speakers. And it would be much easier to implement.
Speaking of leading people astray, BDR cones suck, dude. Well, maybe not compared to nothing.Β 
We now have a proper way to isolate speakers, I.e., mass-on-spring. Isolating them kills many birds with one stone. It prevents mechanical feedback. It isolates the speaker and internal wiring and crossover from seismic type vibration. It reduces unwanted speaker cabinet resonance. Problem solved! πŸ€— You can forget about everything else.
