I used steel coated lead shot in the desgnated base compartments of my VR2s to improve the bass response. It appears to have worked well. The steel coating and isolated chamber should keep contamination at bay. I didn't listen to the speakers at length before adding the shot, because it was recommended by VSA as part of setting them up. I can say that they stage very nicely, therefore, I think the deadening effect, if any, is minimal. I just heard a system that was heavily braced both with lead on top and around the bottom with a total of 4 X 25lb bags per speaker which the owner is certain improved the bass response. I can't be sure if the staging was makedly affected because I never heard the system without the loading.
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.
