UNless I miss my guess, mass loading usually involves the stands, or placing bags of the shot or whatever on top of the device, not inside. As for steel, its magnetic and so I don't think it should go inside a speaker with a magnet. As for lead, it highly toxic and I sure wouldn't want it loose anywhere in my home. Bagged only, I say. YMMV.
Lead shot questions
I have a few questions about lead shot as mass loading for speakers.
Is the shot placed loose internally? Bagged? I really dont like the idea of stacking bags on top of the speaker.
What do you do with the acoustic-fil or liners?
Any pointers on getting the shot inside the speaker? Woofer removal, or input terminal removal, or just a common sense lowest point available?
Lastly, with my B & W CDM-9NTs, do you think it would be a worthwhile endeavor?
Thanks in advance.
