in the pic it has a ported box..... i understand the 2.0cuft after displacement, but the port only has 2 measurements, and doesn't say what it is tuned to...what does it mean? :confused:

can somebody figure out the measurements i need to build a ported box for my 2 12's? slot port in the middle of the subs.(like the pic)
i have the t/s parameters if that helps any..
