I'm terrible at boxes and box design, but isn't that a little big for a 12?

I'm Fi's sight they call for 1.5 - 2.5ft for that sub. So the first box that was netting 3.5 was but how he is sitting right at the high end of the recommendation,  and he is underpowering a tad.  

so far...

No you need to select two baffles,  it's going to cut down airspace.  

You sure about that? Only reason I ask is it does call it an extra baffle... just want to clarify not trying to be a dick

Well if you double baffle,  it is going to keep you within the parameters of what you have selected.  So that means it will place the second baffle on the inside of the first baffle,  taking up extra airspace.  So if you click "1 baffle"  and it doesn't change your net airspace,  one can only imagine that is only calculating the original baffle.  If you click "1 baffle and the net airspace changes,  then you know it really is adding" 1 baffle" as in one extra baffle,  which I how I think you are reading it.    

so far...

When I change from "0" to "1" extra baffle it does change my numbers so I assume it takes it into consideration.  I'm thinking I'm golden

Yeah if the option is "extra"  baffle,  you should be golden.  I was thinking it said just baffle, and I'm not around me computer to look

Man I wish I had good news. I seem to be getting very little output. The sub Is super stiff and I'm underpowering it but it really seems to be struggling. I think the box may just be to big for the output I was expecting...?
