Lead Shot Substitute for Loading Speaker Cabinets?

Silica sand works well. While not as dense as lead, it is non-toxic and more than heavy enough. It can be gotten at any place that sells sand blasting shot. I use it in the stands of my speakers per the manufacturers recommendation. It is also pretty cheap at about $8 for a 50 pound bag.

Go to a gun shop. If you live in denver I have some I will give you.

There's another thread on substitutes

At Larry Staples {original to LSA}house one evening who had worked with Von Schweikert. We removed the shot from his prototype speakers under test. Replaced with direct coupled Audiopoints. Less dark more speed and a much more dynamic stage. He never used fill material again that I know of. Tom

True Tom.
If anyone has the ability to find this--real wool stuffing is remarkable. It may sound strange, but in the old days, Bud Fried, (Irving M. Fried) used real wool in his IMF's and the results were outstanding. Enough so, that in developing the LSA Statements, I substituted real wool for the inexpensive poly material to really great effect.
For those of you who really enjoy a natural sound, try it. Larry
