Lead shots for speaker stand.

Lotuss4. Copper is not a bad material, but in the size and shape of pennies, they won't do much in the way of packing together, not to mention the difficulty in getting them into the confined spaces allowed for filling (on most stands). I admit it is an ecologically sound idea though, copper is certainly safe to handle.

My Atlantis Reference Rack has provisions for filling with sand/shot. But the weight of my stuff on that rack already exceeds 250lbs, so I thought the benefits would be very minimal if any at all! Would I receive any benefits by the extra 20 - 50 or so pounds that silca or shot would add? One concern is the "pendulumn effect" of a very heavy (65lbs) SCD-1 player on th top shelf (necessary, because it's top loading). Does this pendulumn effect have any negative effects, or should I be more concerned with resonance from the components itself (seems most logical)?

It seems that effective resonance control is a yet undiscovered mix of science, trial and error, black magic, and voodoo!

BB's (for the guns) used to be made out of copper (35-40 years ago, anyway).

Thanks to all. I think I'll go for the silica sand instead. I forgot to consider the environmental impact of lead.

I do business with an industrial supplier that carries lead shot in 9 sizes. Size #9 (.080") through .440". McMaster Carr Supply, New Brunswick NJ, 732-329-3200. Pricing is about $50 per 25 lb bag.
