I own 2 (picture under my prophile) and I would not recommend them. They sound great as good as the fathom honestly minus the room correction BUT both have broken twice. The crossovers went bad in both subs within the first few months of ownership. 5 years later both volume pots went bad.
each time JL fixed them. The first time for free the second time for just under $500 each including shipping. The second time was under their rebuild program (yes they break enough there is a program for it?!?). They replaced everything but the cabinet.
so JL has been great from a customer service stand point. I had to go through the dealer which was a pain. But they should not have broken to begin with. Now I am just waiting for them to break again and I will replace them with a different brand.
the only selling point of the E112 is they have a built in highpass with is very rare and very useful.
