REL vs JL AUDIO

Great thread.  I've wondered about the same question.  Having only owned a REL (528SE) and in the market for two subs, this is great information.  Reliability is important as shipping subs back and forth to the mfr for repair is not something I'd want to do.  My use is for music only.

Rel gets my vote using high level inputs

I had a pair of JL Audio E-112s, very fine subs but I couldn't take advantage of the built-in XO...I replaced them with a pair of REL S/510's...and was able to get much better integration with my mains using the high level inputs. 

Appreciate all the input. I have a REL S2 and am upgrading so I wanted to know which way to go. Looks like I'll stick with REL. The Carbon Special looks like the one. 

Lots of rel are made in China ,except upper line  over$2-3k range 
on average , why no adjustable app ,? 
SVS makes  the excellent Ultra 16,
As well as the  3000 SB  that are every good if not better in their price class.
SVS have a great app for all adjustments ,Free shipping, 45 day audition 
if not happy they even pay return full refund ,5 year transferrable 
warranty , does Rel or ,JL do this -Not that I know of ,
And  a bunch of Excellent reviews !!
