JL Audio f112 or f113 sub?

It depends mostly on your SPL level needs. 1 F112 might be enough, if not go for 1 F113 and if still not enough go for 2 F112.

Rel B1 or Studio (if you want to move up), more hook up options and I think faster, and deeper.

If you plan on keeping them 2 F112 will be more than enough. I think the F113 have a better resale ratio. Either way 2 subs always sound better than one IMHO.

FWIW The CS3.4 has a lot of bass already so the main benefit may be to supplement it for two channel and to protect your mains when listening to movies with heavy bass. An F113 should get you around 110 db SPL clean usable LF in your room. That should be enough.

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?
