Even though T3 is out of business PE is blowing their stuff out, http://www.parts-exp...tnumber=269-087 12" 400w RMS isn't bad Not sure of the recommended enclosure specs, but you could probably stuff your box. Yeah, I can't seem to find any box specs on them but I'm sure they're out there somewhere. The only thing I'm not sure on is the cutout diameter. I think they are just a little too big to fit and my last attempt to enlarge a cutout was an extreme fail. Well if it is too big you can always just cut a new faceplate and make it in to an adapter plate. you could always try to invert it too.
