I have used playground sand purchased in bags at Lowes. Be sure to let it thoroughly dry before filling. An alternative which I recently tried on a pair of speaker stands is kitty litter. The kitty litter was easier to use simply because it did not require drying. Please don't ask me which sounds better, I don't have golden ears.
what type of sand to use?
if one plans on filling their stereo racks legs with sand,,,is there a type of sand to use?
thx
