I want to put my experience on the record. Just like nearly everyone said, JL Audio has serious quality control issues. I bought two brand new Fathom F112v2 subs. Setup included measurements, miniDSP, professionally installed, etc. Already had 2 subs that were perfect but was hoping for something more.
One F112 had a broken voice coil on arrival. Just buzzing around 40Hz. They did not integrate well and ruined the sound of my system. Needless to say they are gone. I was so appreciative of my dealer for standing behind their recommendation and making it right. I strongly recommended against JL Audio in every possible way.
