subs for Sonus Faber Cremona M floor standing


My system includes Mac C2300, MC2102. I have it narrowed to the JL F113, Rel or SVS. I am looking to integrate it to the system... Not for the boom boom boom. This system is 2 channel for audio not home theatre. As the SF are amazing I just want to bring a little more low end back into the system. I was running Klipschorns biamped before this so I am missing the walls shaking ;)

I use 2 REL Stadium subs with my Gamut L5s, which are similar in size and frequency response to the SFs. I was looking for a pair of Cremonas myself before I got a great deal on the Gamuts. The JL is suppose to be very good also but I haven't heard them.
I from time to time use a REL Stentor with my Sonus Faber Cremona Auditor Ms.
I used to use 2 REL Stentors and withim the last 48 hrs have been fine tuning a JL f113 which already is outperforming the Stentors! Faster, more muscular and the JL has a sense of effortlessness that is just wonderful.
