What T/S specs should I look at when deciding which box to build?

Like the title says, I'm not sure what kind of box I should build for my next project. My weapon of choice this time around will be the TangBand W8-1363SA 8" neodymium woofers... and 4 of em. I kinda want to try to build a 4th order bandpass enclosure for them, or possibly a simple ported box. BUT I know that the T/S parameters will tell you what kind of box they would most appreciate... but Im not sure what parameters I need to look at, and how some of the parameters effect the performance of the sub. Any help would be greatly appreciated.

I need 80inches here so he can help me out. lol

When I aim for a desired cutoff frequency, thats when output begins to fall off very sharply, right? I wish they had sample graphs...
