I just checked out the website and there's alot of info left out. I was looking at the subs and alot of the specs are missing and there are no box suggestions either, just for some of the 12s. The Death Row and Flatline series look cool. Are they power hungry or efficient? What's the excursion on those subs? I have a ported box, it's 3.5 cubes tuned to 34hz and the amp I have is the JBL 1200.II (puts out 1100 watts at 2 ohms). Would that be proper for either or those series of subs?

Sounds like you need a single Death Row 15" Dual 1. All the subs are very efficient.
