I have owned several different Type R setups (12, 12s, 15) and have always been pretty happy with how they sounded/ how loud they got. They seem to require a good amount of power to get loud vs. other subwoofers in the same rms range. I can't speak to the SAs but forum boners are forum boners, you probably can't go wrong there. It comes down to how much you want to pay also. The 2012 Type Rs are very modestly priced vs. the other options you listed, but at 1krms will probably need a lot of power to really shine. With your power, I'd look at the older Type Rs vs. the other options. They can be had very cheap these days, if budget is a concern of yours.
