Im looking for a sub to provide me with just a little bass nothing too fancy at all and I still want it to sound decent. How is this: clif designs sub cdaw10 sub http://www.clifdesigns.com/productcatalog....g.cfm?class=357 A guy I know has one for sale with a box which is perfect, what do you guys think, how much are these worth what should I offer him? Thanks, Matt
