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
Thanks nonoise those are very interesting!
I had not come across them before!  Ken
OP, did you make a decision on REL vs JL?
Hi Krenooo6, 
I just purchased and received a pair of the REL Carbon Specials.  Very Happy  I was able to change the position and smooth out the booming issue I was having.  I set them ujp with the REL Air Ship wireless, which makes trying different positions a breeze.  Moved them away from inboard of my speakers pointing straight at me, and put them in far corners angled into the space.  Seems to give the sound more room to spread out and less immediate reflection points right back at them.  Anyway, happy with my purchase of the REL's.  Ken
