Actually nick, if you think about it, adding rocks to the inside of a cabinet will reduce the cabinet volume, increase the interior density (say compared to the usual baffling that is used for dampening) and likely alter the sound.
Could you imagine if one were to pour concrete inside the entire speaker box itself?
