The whole purpose of a subwoofer is to broadcast frequencies that a normal speaker doesn't have the ability to. When a speaker's horn tries to push more sound of a wider frequency, it'll spaz out. Ever heard someone's crappy car system try to push a low bass sound, and every time the bass kicks, the speakers get a little quiet? Same concept. If you try to push all sound frequencies through one speaker, you're just overloading it and things start to sound muddy. They aren't a waste of money!
