it's crap anyways, subs in laptops are a waste of valuable engineering space IMO. it's nice to have decent speakers w/ a laptop, but there's not a subwoofer solution in a laptop that will sound as good a simple pair of headphones w/ a good bass response. needless to say if u actually want to listen to music in the open, an external solution is pretty much the only way to go. the sub solution at best will take a crap tin sound to sound average at best, again imho.
