Has anybody tried this for their floorstanders? Do you use special acoustic sand or the normal sand used for construction will do? Is it easy to get the sand in and out of the speaker enclosure? because I assume getting the mix right will require some trial and error.....
Found this on the net note one of the items is in reference to "Bose"
