I completely agree with Marco.
Carelessly applied, a laxative can create colonic trauma resulting in an uneven stream of fecal expulsion and'or volume sometimes interrupted by varying quantities of intestinal gases.
Judging by the thread title, I'm assuming this would be contrary to the desired effect.
Promoting healthy evacuations through proper diet and the use of fiber enhancers can create an environment of large, free-flowing movements without excess collateral residue or loud frequency spikes accompanying them.
If it was sound systems you were referring to, I enjoy mating a tube preamp to a smooth solid state amp which often results in a big, unrestrained musical flow.
