Pairing of different JL Audio Subwoofers

You can add just about any sub. The more subs, the less the need for room EQ. I have five subs, of three different types, and its the highest quality most beautifully integrated bass I ever heard anywhere. Do a search for Distributed Bass Array, read up and understand why the most important question is not which sub but how many. https://systems.audiogon.com/systems/8367One Talon Roc sub.Two 10" sealed subs.Two 10" ported subs.No need to match or pair or anything.

No problem using the f112 with an e112 and use the D.A.R.O. with them.  I am currently using an f110 with D.A.R.O. to EQ/control it, another f110 and an e110!  

This is great news. @millercarbon, I never thought that having more would reduce the need to EQ the room. Thanks for the link.

@kr4, I am glad to hear that you have a similar setup. This gives me all gives me a piece of mind.

Would you recommend I daisy chain them or wire them using the two subwoofer outputs from the preamp?

If you are going to use the D.A.R.O. in one sub to EQ the entire set (as I do), you will have to use a single output from the preamp and daisy-chain the subs.

Are you planning something different?

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. 

I wonder if the D.A.R.O. would still work in this configuration.

Chief, I think you would be better served by getting three more E112's
With four of them you will not need DARO. 

Just read that the Fathom has to be set to MASTER and all others (up to 10) to SLAVE. Then to daisy chain each slave sub with XLR cables from the sub designated the master. When set up in this way all subs are measured and corrected as a single entity.

@mijostyn, you may have a valid point. Since the cabling configuration does not seem to support my vision of using F112 as the slave, I may just have to aggregate one or two more subs. Really don't want to go this route but seems like there is not other way.

the F112 has a XLR output and the E112 does not accept XLR input.

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.

@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.

Another option with JL F series is to use one F series as the system master and daisy chain multiple and more economical E series. Refer to the F manual.
