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.

Hey, d2girls,

if you meant me, I am far under 60. Not that it matters, but for the record. Otherwise, you are right about bickering, but so am I.
Whoa! What! Glubson finally blew a head gasket. Oh, well, that’s the way it goes sometimes. Of course he’s far under 60. He’s 15.
geoffkait,

Not blowing anything. Just reminding you of who you are. Know your limits. They are very low. Your contributions to any of these threads are virtually non-existent. Your random chatter is distracting people who would like to learn something here. Your manners are deplorable. I would like to find a positive thing to mention, but you are not giving any opportunity with your posts.
