Adding two JL Audio F110's to my 2 channel system

Freddy, I also have 2 JL f110's.  They put a solid floor under my Wilsons Sophia 3's.  I'd also like to go the JL crossover route as James suggests, but it's not cheap and will to wait for now.  Until then, here's your confusion; the Neutrik connections on the subs double as balanced XLR connections.  I run balanced out from my McIntosh pre amp, left and right channels into the subs.  I used a test tone disc, a sound pressure meter and the subs own room correction to dial them in.  Although not as good or precise as the JL active crossover, it will get you close.  You're going to be very happy with these two subs. Good luck and let me know if I can be of more help.

James633,
The Jl audio e-112 comes equipped with its own active high pass crossover.  Here is a quote from their website "The E-Sub’s active crossover is a true two-way, 4th order Linkwitz-Riley design, with a low-pass filter feeding the subwoofer's amplifier and a high-pass filtered signal exiting its line outputs."

Thank you all for your comments.  Somehow I feel better.  Yes, I'm afraid the only way to get close to holy grail sound is with JL audio's own expensive crossover unit.  Unfortunately, I don't think this crossover can be used with my BAT vk300x.  I think I have some ideas of my next upgrade.

 Thanks everyone again!

My problem now is I don't think I can use a crossover unit with my BAT 300x integrated.  Don't think it has appropriate connections on rear panel.
