The subwoofer certainly makes a big difference Hooky doesnt it
I have a Labtec subwoofer and satellite speakers that are only about 3 inch square, maybe less and it sounds better than my home mini hifi system
I also have it connected to my home cinema 5.1 surround system via s/pdif on co ax so I can get even better sound if I want but the normal pc speakers and subwoofer sound fine for music normally
