REL 12" Carbon vs JL Audio 12" Fathom

I decided to make a new thread on this.  Plenty of people love both of these.  I am looking for two new 12" high end musical subs for two channel audio.  I am familiar with and LOVE the REL Carbon Limited's. The New Carbon Specials are supposed to be even better.  But now I am looking at the JL Audio Fathom F112v2's.  Because they have EQ that would be great for my boomy basement.  I want: 12", super musical and fast for high end audio.  I also want EQ. But are the JL's as musical as the REL's?  We are truly comparing similar spots in each company's line...12" sealed, $4000 list.  Would love to hear from folks who have compared...Happy Holidays!  Ken
