This is a box I drew up for my 2 Audiobahn 12's. I used the RE Calc to figure up what 1 would be and then just doubled it and cut the middle out of the two. I think it is around 5.4 cuft before sub displacement. The subs each displace .2 cu ft. It is tuned to around 34.8 hz. It has around 46.2 sq in of port. The subs will be up and the ports firing back (SUV).
Is this math correct or am I so far off its not even funny? I am just a teenager playing with some designing so tell me what you think? Any tips or tricks to use in the future?
