Looking for a sub thats gonna murder the lows.

well, shit, man you are tuned to 38 hz, and probably peaking around 50hz with what?...F3 of 28hz? Just a guess...you have a lot of sub there to work with, if you get the box right.

You just need the right box, dude....what power you got?

Its on a MA Audio HK2000D roughly 750ish RMS @ 4 ohm

Could I go with 2 CF or larger and tune it lower?

I agree your box is tuned to high

How is the box mounted right now?, what is the layout? sub/port on the same plane? what vehicle is it in?

I'd go 2 to 2.5 tuned to 30ish
