In response to the remark that Bookshelf speakers cant play as loud as Tower speakers thats false .
Another advantage to useing a sub along with a nice set of bookshelf speakers is the fact that you can place a sub in the best location within the room to address room acoustics. Very seldom the best location for low freq's is the same as the best location for the loud speakers . You can really tame some of the low freq responce issues in a given room by simply re-directing the low freq's to a sub located in the best spot in the room.
