mine is one of the smaller ones, it's not the one with the huge driver though, the sub itself, i sh!t you not, weighs as much as my MOFO15 and the driver is not only thinner and much wider but the frame is cast iron. And these things are like Cerwin's they just won't blow lol, believe me i tried it with my A2400DB >//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
