I got this one for about the same price. I paid 350. It is a molded subwoofer box. The dimensions look about the same, and mine came with 2-10" MTX subwoofers already mounted, and wired. It is basically just plug and play. There are also three different colors to choose from. I got the loaded tan one. It is 400 watts RMS, and this thing rocks. The dimensions are given on the page. I really don't like the way Quadratec hosts its products. They tend to not give the important specifications, and when you buy it, and it doesn't fit, or its crap, you really can't return it without a big penalty.
