Well I already have a shiva in a sealed 1cuft box that I'm running 600 watts to... but I just got some extra spending cash for xmas. 
I wanna purchase a second shiva, and I feel like going ported. First question: I think I have the older non-mark IV shiva. I can't remember which one I got, but I got it around 12-13 months ago. Was the Mark IV already released around then? Second question: If it is an older version of the shiva, I'm assuming it wouldn't sound too great to buy a single new one and add them together? How bad? Third question: I gotta reserve some trunk space cause I travel back and forth from college to home a whole lot. Is it possible to get a good combo of SQ and SPL from a dual shiva ported box that doesn't go over around 2-2.5cuft? I want it tuned pretty low (in the 20s) I think. If I made it downfiring it'd save a little bit more room horizontally. What does everyone think?
