Looks a lot like the old Rockford Fosgate Punch Power Reference series made around 1999 or 2000. I would have posted a pic of mine but deleted them a while back when I sold them. The main thing that mine had was the dust caps were plastic molded with a very obvious RF molded in them. If you look at the caps see if you can tell if they were replaced or not. If they did it correctly you won't be able to tell though. A front picture would help also since the outer seal rib and surround can help to identify speakers easier than a basket design, specially with no real close up of them and spider assembly. That is cast not stamped correct?
