Try something else. In my experience lead destroyed much of the microdynamics of the music, especially at lower volumes. Sand much less so, but created some resonance issues. I took a hint from the AudioPoints folks and tried fine metal shot (blasting shot off ebay). Sounded very exciting and energetic, but a bt unnatural. A 50:50 mix of steel shot and sand was just the ticked to retain microdynamics but still sound natural.
I also don't like what high mass does to the sound of my bookshelf speakers, and I didn't like the effect of blue tac, but those are lengthy topics by themselves.
Try these things for yourself.
