REL vs JL AUDIO

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 !!

@audioman58,

A close friend of mine just dumped SVS and switched to a pair of REL Carbon Limited. REL comes with 60 Day home trial and free shipping and returns!

That says nothing a empty statement- they sold there SVS sub ?,Svs has   Over 8 models , and both the3000SB,4000 and ultra 16 SB are loaded with accolades around the world .I have had both rel and JL audio and dumped them which were $1200 or less it all depends what model good and bad in all , I love  the SVS  sub app all adjustments from your phone or tablet.
