atabites and/or other speaker fillers


I recently researched an Atabites product available at [url]http://www.atacama-audio.co.uk/prod-f.htm[url\] and I want your opinions.

I found out that these triangular shape high density steel chips are magnetizable. Can they affect the speaker drivers and the voice coil by embedding an additional magnetic field within certain period of time? I believe that the speaker curve or the coil responce might change...

I also want to discuss whether the monitor stands from ferromagnetic substance are OK for the speakers as well.

Lead shot is the way to go to fill up speaker stands. No worries about magnetic properties. Given the rate that magnetic force diminishes with distance, I doubt that there would a significant interaction between a speaker and it's stand. An exact calculation of the forces would be complex.
All commercially available Lead shot is required by law to be plated with Bismuth. Don't eat any and wash your hands afterward, and there should be no problems. Even if it wasn't plated, elemental lead is poorly absorbed by the body. Lead poisoning usually results from ingestion of soluble Lead compounds such as Lead salts.
