What to fill Skylan stands with for Harbeth SHL5s

My wife has acquired a taste for Native Indian pottery. She decorated an area in the music room with the expensive vessels. They had a tendency to hum along with the music, but after filling them with sand (2 dollars for 60 lbs at Home Depot), they actually make the acoustics of the room better by removing an echo...they are absolutely DEAD when tapped.

I'm using 24", two-post Skylan stands under a pair of EOS HD monitors. I found Noel's stands to be a bargain, well-designed, rigid and non-resonant when filled with a combination of lead shot and washed playground sand. I used 6 lbs of #9 lead shot mixed with about 14 lbs. of sand in each post. (About 40 lbs./stand) The lead shot is mixed with the sand from the bottom to middle of the post; sand only from the middle to top. While the results are quite good, I'm going to add more shot and sand and have a listen to see if the added weight makes a sonic difference. I also use 4 Herbies Audio Labs Square Fat Dots under each speaker. These are specially formulated for loudspeaker decoupling and are quite effective. They will tame floor resonance, tighten the bass, and allow more detail to be revealed in the music. One Harbeth SHLBs owner who uses the Fat Dots claimed "the sound opened up considerably."

I meant to say Harbeth SHL5s in the previous post.

Try using 6 DH Labs Ceramic Cones (small ones, points up) from Golden Sound and listen to the magic.

They will not harm the speakers finish, because points are slightly rounded and are finished in gloss black.

A synergistic match with Skylan Stands.

Use kiln-dried sand. This is all you need, and it's cheap. Buy it at your local home hardware.

Don't bother with lead-shot, cones, or any type of 'filler'...it does not and will not affect sound quality.
