I have never used R's, but for some reason the SE's are still one of my favorite subs I have ever used. I have had 5 total, sold em all and regret it every time. Im actually looking for another one right now. They are great SQL subs...
Ed 13.o or 16.o would love that much power they are pretty efficient subs. I have bought a 16o from them b4 and no problems. got insanely loud with 900 watts.
