Pairing of different JL Audio Subwoofers


I have an E112 subwoofer and I am looking to add another sub. Can I add a F112 to take advantage of the Digital Automatic Room Optimization (D.A.R.O.) system? Or should I find another E112 to pair it with?

A xlr to rca adapter should get the job done.
Indeed, I have an XLR-Y cable connected to the XLR output of the master f110.  One leg feeds the other f110 via an XLR cable.  The other leg feeds the e110 via an RCA cable.  
@imhififan, this may be option. I hope there isn't too much degradation, at least nothing audible.
Any specific brand recommendation for this XLR to RCA adapter?
I've used Kubala-Sosna and Cardas adapters with satisfaction.  I've had variable results with the cheaper Hosa adapters.
Thanks kr4. After some sound boarding with you all, I think I will pull the trigger on getting the F112 after all. Time to search for this adapter. 

Thanks for everyone's input. I truly appreciate your experience and words of reason. 
This might be a problem as the F112 has a XLR output and the E112 does not accept XLR input. I would have to use the RCA output of the E112 to input it into the F112.
@chief_trojan  Jensen Transformers makes a transformer that is optimized for subs that will do the conversion from balanced to single-ended or the other way. It has bandwidth down to a fraction of a Hz so it won't interfere with bass impact. I'm using a pair of them in my system.
