Filling speaker Stands?

I have a modest system. Continually look for ways to improve it's performance even to a slight degree. I have read many posts about improvements than can be achieved by filling the hollow spaces of some speaker stands with some type of material....sand, kitty litter, lead shot, and some others. Here are the stands I have......

These stands are of metal construction. There are 2 upright support tubes which are approx. 2" diameter. The stands sit on a carpet floor with spikes. On the top plates are a layer of Sorbothane and PSB Imagine B speakers sit on top of that. The 2 metal supports are attached to the base and top plate with just threaded holes about 1/4 " diameter. Pouring some type of dampening  material would definitely require a funnel.
The reason I ask this question is that, when I thump on each upright post, it rings for several seconds. A dampening fill would minimize this but would filling those posts really benefit the speaker performance to even a small degree given my modest setup? I don't know. Probably, few have experimented with this type of scenario.Thanks for any advice.

If you use sand, only use stands that are welded, stands that have bases or parts that are screwed or bolted together might cause sifting in the cracks.

Silica sand is non-organic, very dry, and is available in many grits. I chose the grit that was the smallest of those most resembling organic sand, but not powder-fine. I believe it was 80.

jrpnde .. I don't think 1/4" is large enough to accept the small pebbles. As long as your bases are welded, sand might be a good option for you (not beach sand). You might also check out steel shot.

Lead.

It does not ring like steel and substantially increases the stand mass over sand, steel, pebbles, etc. Best would be lead filled with sand.

Sorbothane works very well in coupling the speaker and stand. The improvement in mid-bass detail is impressive.

Kitty litter is far too light to be of any use.

As far as disposal, almost any gun club can direct you to a reclamation center. Simply add a label on the back stating the stand is filled with lead shot in the event the owner is not the disposer.

How about a molten lead where you can pour inside the stand which will fill up every small spaces then let it cool down, would that work?
