Lead shot questions

i may be wrong but if you put lead shot inside speakers that were not designed for it you are taking away from the internal volumn of the speaker as it was designed.

Very good points and ones that I had not thought of at all.

I saw an add here a few days ago for very small stainless steel discs. I suppose the steel wouldn't create dust like lead. At the very least, it wouldn't be as toxic.

If I remember correctly steel weighs approximately 4oz per cubic inch. Discs would be less, since there is some air space, say 20% less. Hmmm, 100 cubic inches for 20Lbs as a guesstimate. That's a fair amount of volume, 4 to 5 percent of my speakers internal volume, certainly enough to have some acoustic effect.

Nonetheless my curiosity is still piqued.

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.

Elizabeth is right dust would be dangerous to young childrens nervous systems. It may also make you snap for a moment in a rage of anger, & who knows?

First pick up a pair of Sound Anchor Cradle style bases for your Cdm-9nt's, then going from a Bryston 4b-st, to 7b-st mono's will really open up the 9's BIG TIME!!!

The Cdm-9's are fine as is no need to mod them, they just need a major amount of juice to really open them up. I used to own a pair w/ a 4b-st, & 2 Rel Strata III's. Once the 7b-st's where in the system I never felt the need to re-connected the Rel's.

Good Luck!
