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 thought about putting sand or shot in my KEF Reference Two plinths but am wondering if it's worth the hassle? They are dead solid, basically no vibration even at very load levels. Since they may not vibrate as much as other speakers, will loading the plinths offer even less benefit?
