Lead Shot Substitute for Loading Speaker Cabinets?

I am using Micro Bearings from Star Sound , which is like steel sand, VERY heavy and Attabits (sp?), small steel shot which is imported by May Audio. Both are not cheap, another thread on this suggested steel blasting shot, which I haven't tried. It should be cheaper.

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
