JL Audio e112 or HSU ULS MK2

Heard the HSU subwoofers and also met Dr. HSU (awesome and very humble guy) 

The ULS sounded bigger than it looks for sure. I really liked its sound quality. The only thing stopping me from buying HSU is the Rythmik F15's piano black finish which I prefer. 2 15 inch rhythmiks are costing me twice as much as 2 ULS. HSU's price is crazy good and at this point I dont know if 2 rythmik F15s will be twice as good as 2ULS 15s. 

If cash was no object i would get the dual 18inch sealed Rythmik. 
@bdp24 I know you suggested that I get a single 18inch but I think dual subs are easy to integrate than a single sub no matter the size..

Btw I live in Chicago not California 

Dan, please re-read my above post. I did NOT suggest you get a single 18" sub, I said if you're going to have a single sub, the new 18" Rythmik would be killer. I'm going to stop posting, my words are too frequently misunderstood and/or misquoted.

@yakbob
Could you go into a little more detail about sound, placement, room size, and how you connect your ULS-15's in your system?

I cannot even begin to describe how much of an unfair comparison that is.  The E112 is a dramatically better sub.   I owned one, and then a pair, of ULS15's.  I loved them, but didn't know what I was missing.  Not even close in performance, especially for music.
