im building an enclosure for my 12" L7's and i need to find out what im tuning it at. i already cut the wood as someone drew up plans but forgot to write down what its tuned to so can someone tell me and if its not sufficent then tell me what i should tune it to for deep deep bass.

is the box divided in the middle? is their a divider board that allowed each sub to play in its own chamber?

**this is for a single port for both subs in shared space**

5.6 cu ft^3 @ 27 hz

port face 3 x 13.25 length = 18... thats with a single port but yet you have two so don't even regard this

2 ports single chamber. im about to seperate them though. so thatd be roughly 2.7cu
