Just stumbled upon a good idea to improve your speakers...
Problem:
I wanted to make my speakers more stable and more theft resistant by making them heavier. I looked at sand, but a density of around 2.5 g/mL meant a bigger cabinet which I didn't like so much. I thought lead would be good with a density of 11 g/mL.
Solution:
Lead shot costs $25-30/10 kg bag from reloading supply stores. I decided there must be a cheaper way so I visited the scrap metal yard and bought 30kg of lead sheeting for $0.70/kg!
This was melted in a fire in a dog food tin and poured into an MDF box, set on pavers and lined with aluminium foil. The ingots are glued into their own compartment with loads of construction adhesive.
The result:
10 kg lead ingots added to the bottom of my speaker cabinets, making them only 2 cm taller, but more stable and able to resist all but the strongest of thieves.....
Only wish I bought more lead.....
I'll post finished pictures when I'm done.
