Filling my speaker stands to weigh it down?

you can buy a 50lb. bag of play sand at Home Depot for about $3.00

I invested in about $200 in lead shot to keep for a long time! IF I ever sell stands, i just empty the shot into the next pair of stands. It's worth the investment to me.

if u put the lead in the fridge before u fill into the stand, the lead will be tight in the satnd when it warms up.

Yep, empty cavities have a tendency to resonate. So while you're at Home Depot checking out the kiddie sand, which typically contains pebbles and is stored outside in the damp, for a coupla dollars more splurge for the contractor's grade silica sand, which is dry, uniform and stored inside. In December 1999 Home Depot asked $3.90 for a 50lb bag.

Btw a plastic funnel works wonders for carefully sifting the material of your choice into the stands. Of course, if your stand isn't a sealed, all welded design, as noted earlier the fine sand may leak out without a liner.

I use Home Depot sand -- costs only a few bucks. Otherwise, the stands resonate like gongs.
