I've got some Paradigm Signature S4s on the way and the J-23 stands. I've always had floor standing speakers in the past so this is my first experience with stands. One of my concerns with fill is moisture, so I wondered if Oil-Dri might be a reasonable material to use. My local Sam's club sells it by the 50 lb. bag, and I happen to have an unopened bag at the moment. I don't believe Oil-Dri is corrosive so I don't think it would hurt the stands, but as I've only used it on epoxy covered concrete that may be an incorrect assumption. Good idea or bad idea?
