Isolation Sand Box

I built this for a Rega Planar 3 that had a rumble problem. Here is one of my design drawings.

Re: Isolation Sand Box

Once again I start with a basic box made from some scrap MDF.

A quick shot of black paint.

Then some then weathered stone finish and six coats of semi-gloss Deft lacquer finish.

Then I filled it with 25 pounds of glass beads used in bead blasting. It is finer than sand. I topped this with a sheet of glass.

Re: Isolation Sand Box

Add the Rega and it was dead quiet. All this sits on four Daruma Isolation bearings. So you get both damping and isolation.

Re: Isolation Sand Box

Very cool! I could use something like that. My player is in a bad spot and I don't have the room to relocate it.

Re: Isolation Sand Box

Beautiful looking turntable base, but I canīt imagine any special engineering foundation for the design!
What am I missing, that differentiates it from a slab of marble or any other heavy weight mass decoupler?
