Weekend Project for boredom: box for my 12w7. Anyone care to chime in?

I'm bored at work!!!

This will be, as stated, my 4th box for this sub. The original was a sealed JL ProWedge box. I changed to another box snake-ported & tuned to about 29hz @ about 1.8 cubes after displacement. I then got a sedan so I needed something smaller; this is my current box. I tuned this one to 27hz and have about 1.9 cubes after displacement.

Well, after building a false-floor everything got messed up (space wise) I'm looking to do another box. I was going to fiberglass, but I might just try to build a wedge-shape box to squeeze out as much space as I can in folding seat area. I'm really trying to decide what I want to do with this box. I'm thinking about 2.2 cubes @ 30hz. I love this sub tuned low, but I feel like I'm missing some "umph" up higher. If I tune higher, but add more space, will this still help me in the low-end? Toss out some ideas here guys. I'm open to anything right now. I'll be getting a 4x8 sheet of 3/4" MDF Friday for $6 from a friend's shop (he owns a cabinet making shop) so I figured I'd try MDF again before I commit to fiberglass. I still would like to do fiberglass to have a "perfect fit" but I think I'm going to run into too many problems.

Cliffs: Building a new box. Looking to keep low-end but get some more out of 40-50hz range. 30hz and 2.2 cubes good for this? Give me your suggestions.

the current box looks fine to me. i do know in my civic it was the loudest sub forward , port firing to passenger side. I doubt your going for all out spl, but if you give that a try and again tune low, it should sound very nice and be a tad bit loud

Sealed off from the trunk of just the ported box facing the windshield?

sub firing towards windshield, port firing to passenger side. i accomplished this by having the aero ports external. The trunk was in no way sealed off.
