Not sure how old it is but I know that it has an external amp. I looked on the SVS site and they don't sell this (CS ultra) model anymore. I guess that would be a good question to ask the guy. I wonder though, as Glocks says, if this will be too sub for my small apartment. My neighbors have never complained about the sound but I'm thinking this sub will test their patience a lot more than my current 150W HTIB sub.
