I think I've tried every configuration that makies sense, only to be confronted with failure.

At first I thought subs stink. But after listening to my son's setup (the main speakers and sub are BAD), I think there may be hope.

With those garbage speakers of his, his sytem sounded quite nice. Surely I should be able to pass him in leaps and bounds.
