Left speaker rattles, should I make use of the warranty?

Hi, I've just noticed that the left speaker on my alienware 15 rattles at around 80% volume (with the SBX Pro Studio on it rattles at around 50%) on bassy music, should I call Dell for warranty or is it common on this laptop?, I know I know, grow a pair and get some decent speakers but is just that my old HP Envy 17 had such a great speaker system that I miss that.
