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.

Lead shot will kill the stage. Tom

Working with one manufacture to tame a resonance in the bass range..They used mass loading in the cabinet to squelch the peak before the newly redesigned woofer arrrived for replacement. They asked me what I thought .."Speaker sounds coherent but slow and shut down..You need to take the lead out"..After the lead was removed the stage opened up and back came the speed. That was the first step..The second step is another story..Tom

Its not a cure for the bass or any other frequency..Its a sponge that sucks the life out of the speaker or the stand filled with shot underneath. The lead is not sensitive to any selected bandpass of frequencys..They all become screwed up.Tom
