Filling audio rack tubes with sand, metal, grape nutz???

Let’s see, what’s for dinner? Bar B Q Robert? Let me think about it....

It’s no fun being no. 2, is it Robert? And all this time you thought vibration isolation was impossible. 😬

Actually glass microbeads, which I mentioned earlier, on this or similar thread, work better in this application than steel microbeads. Glass microbeads are employed in my Mikro g seismic platform, introduced a couple years ago. Why glass microbeads, you ask? Because they are harder and lighter (react faster to vibration forces) than steel microbeads and because they can be fabricated in the most ideal, efficacious diameter for audio applications. Steel microbeads by comparison are slow and sluggish. Glass microbeads in conjunction with contrained layer damping and a layer very hard material simulates the physical characteristics of a woodpecker’s head. The physical characteristics of the tissue and bone surrounding the woodpecker’s brain 🧠 prevent injury or death during very rapid and extremely high negative g movements whilst pecking wood. Necessity is the mother of invention. He he ha ha, he he ha ha!
