I think I want to go sealed. How big of a box should I get, I have plenty of space, and what should i tune it to?

If you are going sealed, you cant "tune" the box aside from eq's etc. Sealed should be good. Ive never dealth with this sub, but i would think the manufacturers recomendations would be fine. http://ascendantaudio.com/assassin12specs.html

They recommend 1.2 cu ft. per sub. I would try that, but someone who has used them can tell you better.
