JL Audio f112 or f113 sub?

Thanks for the responses. The Thiel cs 3.6 had plenty of bass for 2 ch stereo listening in a previous house. In the current house, the CS 3.6 speakers lost allot of the bass due to poor room acoustics. I assume a sub will help bass compensate for the poor room acoustics. Ideally I would like 2 f112s, however, I normally do not listen to loud music and assume a single f112 or the 113 would be adequate. Any thoughts on if the f112 would be a little fater and possibly integrating better than an f113?

Thanks for all of the responses. I am going to start with a single f112 and add another f112 at a latter date if needed.

Thanks for all of your responses. I went with one f112 to start. Am very happy so far. Have ~ 10 hrs on sub. Sub sonds better with a few hrs, but still needs break in time.
