Default Dual 1.3 sealed - what aero's to add/subs that will do well?

I found a nice box for cheap on cl. 1.3 sealed each chamber. 1" mdf.

What aero ports will I need for 28hz tuning and what 12"s would do good with 1.3 cubes each?

Preferably dual 2 so i can wire down to .5 and give them 2k or whatever a saz1500d v1 will put out at .5

Ports inside the box? If so you will lose space inside the box and need to use a smaller sub

How long would they be outside of the box? I've seen 8" wide aeros that were 2-3" outside of the box - would something like that be pheasable?

Would aero ports inside the box act as if they were a solid tube - taking up the entire outer diameter away from the internal space?

Perhaps converting it to a single 12" and finding a sub that would do great in about 2-ish cubes? (assuming sub displacement and aeros tale up .6 cubes?

I do have a treo ssx 12 but its 1.3 final impedence. I think i remember it needing a lot of air space but would it really get down on only 1300-1500 watts? Isnt the rule that if you give it lower power, make the box smaller? If so, doesnt that hinder the low end response drastically?

Yes ports inside the box take your air space like a solid tube, what the LxWxH of the box?

No way you can fit enough aero inside a 1.3 ^3ft chamber and put a 12 in it and get tuned to 28hz. I'm.guessing that a 4" aero tuned that low would be well above 20" long. Maybe 30" you're better off taking out.the divider and making it 2.6 gross for a single 12 and go from there.

I'm guessing that they are 2 individual boxes connected to each other...he said there is 2" in the middle.

Sounds like this would not be worth it. He only wants $30 though.
