Metal, you say? A musician buddy of mine had these for sale:

Free air resonance 51 hz

I was going to try them in home as subs, but they don't reach down low enough.

4 of those 18"s in a suv playing some winds of plaugue your brain would explode

Well, the poll didn't make that much sense, anyway. A true subsonic system will go well below 32 hz, and to do that with reasonable efficiency, a ported box is called for. I prefer passive radiator or resistive reflex (aka aperiodic).
Sealed box for 60-80 hz or above.

6Th order bandpass.

Because if you dont have a clue you will self destruct subs and seeing carnage is cool.

Different subs, different boxes. Different tastes, different boxes. Different tastes, different tuning. And it goes on.

There is no sure fire.
