Sand filled speakers please help


Can anyone tell me what the purpose of filling your speakers with sand?? I have a pair of Joesph sand fill-able speakers and I want to know what will it do for them if I fill them with sand? will it have better base? will thy sound brighter? I want to know how it will change the sound with or without sand. I like my sound on the bright side. so should I fill or not fill. Please help
Thanks

I filled the base compartments of my speakers with steel coated lead shot with a notable improvement in bass control. I can't say that the damping effect it had will be true for the Joseph's but that is the concensus. Therefore I would think it is the most likely outcome. I have not heard that it yields a bright sound.
