Recommendations for speaker stand filler

Hi Scotty,
In the past I've used sterilized sand which I purchased at
Home Depot.

Also, I just put together a pair of stands for my mom and
I used pure crushed marble. Simular consistency to sand,
but granular like salt, but the grains are larger than salt, tho still very small.

It was very dry, no moisture like you may get with sand,
and very dense and heavy. I preferred it over the sand.
Also a Home Depot item

2 pages of nickel plated lead, steel and bismuth shot. MMMMmmmmm, bismuth shot.

Regular, unscented kitty litter (do not use the type that clumps when it gets wet) has about the same weight as sand but is less likely to leak since it's a coarser material.
