I don’t think the “seashell lead shot” is heavy enough… it looks like the heaviest they have is 8#. But, it is in nice wrapping/sack. But, as I said earlier, you can wrap whatever cloth around it for esthetic appeal.
Lead is the most “dead” of all the metals I know about. It absorbs sound and dissipates it.
In equipment cabinets or speaker stands, filling the posts with lead shot or a mixture of half lead and half kiln dried sand, which you can buy in bags at any building supply, like Home Depot, really does wonders with the music. It’s a combination of a very inert material and mass loading. You can use all sand, but it doesn’t have the mass weight that lead has. Sand alone is better than nothing, but not near as good as at least a mixture of half lead.
If you purchase a rack or stand from Sound Anchors... very heavy and well built... they use hollow steel posts but fill them with some inert material of their own. You don't have to tinker with their stands so much, but it might help to still put a bag of lead shot on top of the speaker itself.
What happens in a speaker when there is no filler and bracing inside the cabinet? The cabinet vibrates/resonnates the sound back to the drivers and distortion is induced. So, the manufacturers of speakers go to great lengths to dampen the cabinet vibrations so the sound will be cleaner. But, they are not gonna ruin the esthetics of the cabinet with mass loading on the outside... but, you can and the soundstage becomes even better.
You know, years ago, there were all kinds of rumblings made when a speaker designer/manufacturer by the name of Bob Fulton came out with huge 2 gauge speaker cables that looked like big welding cables. It took special solderers to even solder the speaker lugs on those beasts. And everybody started poking fun and saying that their 12 gauge zip cord that they bought at a hardware store was all they needed. Then some audio crazy engineers started running sine waves thru Fulton's cable and the zip cord. The difference on a scope was revealing... the zip cord had all kinds of spikes throughout the frequency range... while Fulton's cables were very clean. Then others took off with the idea and many cable companies have sprung up even with power cables. And every cable has its own flavor.
So, you doubters... go ahead and do as you please. Don't listen to a guy who has literally spent hundreds of thousands on audio in his lifetime and has tried every tweak to make it even better. My wife says i'm obsessed. That's actually what real audiophiles are... possessed... always wanting to make it a little better. If that wasn't true... then why read these forums and why buy something different? Or try something different?
I'm gonna buy some more shot tomorrow.
