    hi Alman

have you by any chance tried some of the EMI absorbers (either pads, or tape or even crystals)?

    小弟正是想要這種鋼珠沙, 不過要幼細好多果種, 未知邊到會買到呢?

    u want smaller ones? i thought 0.5 mm is already pretty small, but i've seen 0.2mm on Taobao, but they mainly sell for industrial use

but u can try to ask the sellers to buy small quantities

and if the material is 鎢碳鋼, it should have no magnetic or other effect that will interfere wi the speaker right?

    what do you plan to use as the cover of the sand bag?

i was thinking to hand stitch either leather or maybe some other easy to find material (nylon, cotton, etc)
