Of course. Fill em up with broken glass and sea shells if you want. But that’ll work fine too.
Pea gravel is much cheaper. I used some putty at the bottom and took my time filling the stands. (Can do that outside to minimize dust if that’s a concern.). If you go that route, let the gravel dry out for several days before filling your stand.
I sene possibly resonated noises with lower frequencies.
Just put some cheap workout hand weights that have a rubberized outer coating.
Grossly overpriced. We used 75 lb bags in monument factory. At Amazon price, we would have sought bankruptcy.
I remember "steel shot" days fondly. This was before OSHA intruded. Trained at age 12. Load 5 or 6 bags in hopper. Monument was polished with rectangular cutouts on a rubber medium. As long as the nozzle never stopped moving, rubber medium protected polished surface. Learned the "art" quickly due to painful spray back. The steel shot roughened the surface. Just the right amount to avoid pitting. Pitting resulted in painful recriminations from grandfather and father. Sandblasting was another story. No trust until 16. Very difficult and high skill level. One worker passed out in sandblast room after night out, and Dad found him with 4 inch depression in granite slumped over the nozzle. Thank God his face stayed away from the nozzle.
Use silicone for it's fundamental frequency (9.5 Hz) if you don't want any ringing.I was thinking of using this instead of sand in my speaker stands. They ring like a bell unfilled. Has anyone tried using spray foam sealant?
