What to fill Skylan stands with for Harbeth SHL5s

The best thing to fill stands with is lead shot; but it's expensive.

I filled the bottoms of my Target stands with 20lbs. of lead shot (20lbs. is not much shot, but it makes a huge difference IMO).

I filled the rest of the stand with playground sand.

I've read about people using kitty litter, I think that is ridiculous. You want to make the stands inert to vibration, and lead is pretty darn inert.

I used sand on my Skylan stands ( 20" high 4 post ) filled aprox 2/3..I used construction sand ( in tubular bags )...Its a larger sized sand and works great..The real trick is to not over fill...You can over do it..I found 60-70% worked best for me...You can try 50% and always ad more if you need to......I also found that using the Big Fat Dots ( or similar ) for transition between stand and speakers works well...

I believe that Noel at Skylan recommends clay kitty litter. Try calling him and asking; he's a great guy and easy to deal with.
