Well let me start by saying that I am not a subwoofer guy, by any means. I just read what is posted on here by others and point out the other options out their for people looking.
Both of those look good, the only thing I can say is that the three that was posted are a good bang for the buck. I looked up your front speakers and you do want something that can go low and it looks like all the sub can do it. Then again if you are looking to save some money the three subs are hard to beat for $700.
If you can try to pm "The Ear" for his opinion on this matter, he is the real deal when it comes to subs. Also check out "Michael Hurd" beast that he is building.

Got stopped at the mall the other day
Heard a call from the other way
that I just came from, some ni**a was sayin somethin
talkin bout "Hey man, you remember me from school?" smoke some
Naw not really but he kept smilin like a clown
facial expression lookin silly
And he kept askin me, what kind of car you drive, I know you paid
I know y'all got buku of h**s from all them songs that y'all done made
And I replied that I had been goin through tha same thing that he had
True I got more fans than the average man but not enough loot to last me
to the end of the week, I live by the beat like you live check to check
If you don't move yo' feet then I don't eat, so we like neck to neck
Yes we done come a long way like them Slim a** cigarettes
from Virginia, this ain't gon stop so we just gonna continue
