I was getting some rumble from my old Rega Planar 3. So I built a simple MDF box and sprayed it with some textured stone paint.

I filled it with 25 pounds of glass beads and put a piece of glass on the beads.

Cheers!

It looks very professional indeed, did you use wood to make the box? I actually have no idea what MDF stands for. :? This looks like something needed for my turntable, it has no feet or bottom cover because the old one was warped when I got it, so I just have it sitting on a solid pine shelf.

Medium Density Fibreboard.

"wood" made from extremely fine compressed sawdust and glue. Silly easy to work with and moderately easy to finish (unsealed, it soaks up everything), doesn't like moisture. Dust is bad, wear a mask. Weighs a tonne.

Cheers!

oh, yea, that stuff! :) It warps easily and likes to grow mold. :mrgreen: I have an old speaker cabinet I use as a bench stool filled with junk and garbage, has a hole in the top that my friend made with the crow bar when I wasn't looking so stuff kinda falls in and collects inside.... I don't clean it at all untill the box decides to fall apart and need to throw it out, so..... things start to grow, if you know what I mean. ;) :mrgreen:

But on the other hand, if it is painted as shown, it should be well sealed from moisture making it a very cheap and robust substitute for wood. :up:

Hi.

Why glass beads & glass plane? For the weight or its being handily available?

IMO, I would not use any glass to support my equipment. The acoustic resonance of glass lies within human audibility. We can witness a soprano breaking a wine glass when her hi-C pitch gets enough energy to match the natural vibration frequency of the glass (typically around 2,252Hz). A glass pane resonances from 190Hz to 237Hz depending on the glass pane size.

It sound peaky to my ears, period. I am using granite slab & marble slate to support my amps for its mass & less colored sonically.
