I have not heard the others, but you cannot go wrong with the JL 113, espcially for music. They are not the deepest of subs, but they can keep up with the mains in terms of speed and truly dissappear.
I would take two F112s over a single F113. More even bass response in room, possibility of stereo placement. Also rumor has it that JL employees prefer two F112s as well.
