where does one buy leadshots for loading spkrs?


as you can see, i am somewhat new to this hobby. i have a pair of totem arro's and trying to tighten the bass by loading down the speakers. there is a hole in the back and i assume that is what it is for. i was told leadshots work better than sand or better yet a mixture of both. any inputs pertaining to the arro's will be welcome.
curtis. p.s. i use a rega planar3 with audiotechnica m44e and heavyweight on the rb300. also a bryston b60 and an acurus phonostage. much thanks.

If you decide to use sand, don't use generic play sand. It will hold moisture. Go to a home improvement store and ask for silica sand. It's usually found by the cement.
A dealer freind told me a true story of a customer. The stand manufacturer of 10 years ago recommended filling the stands with leadshot to tighten up the base response. His customer then went out and bought 50 lbs of lead at his local gun store and rather carelessly started to fill the stands. He spilled shot all over his carpet and as it was of a very small size was unable to pick it up. Neither would his vacuum due to the weight. The man then called my friend as to what he should do. He told him to contact the state EPA. To make a long store shorter after 10000.00 in clean up fees and a lawsuit against the dealer and the stand manufacturer his carpet is now clean.
Let's see......

Lead has been banned from paint since 1978.....a 10k Federal fine if homes built prior to 1978 don't have a Lead-Based Paint Disclosure provided to potential buyers when marketed.

Lead has been banned from auto fuel for many years...

Several states have banned lead shot because of water and waterfoul polution/health concerns...

Try to find a different solution rather than lead shot.
