I have two Memphis Power Reference 104d (DVC 4 Ohm) they are in a slot ported box and i do not know how to figure my tuning frequency.
If i post the dimensions can you help me figure this?
I bought the box from the car audio shop that i bought my equipment from, it was previously used for the same model of sub.But the guy who traded it in went with 15's

the box out side dimensions are 32" w,16 " h, 14 "d
the port is in between the the subs it is 2.875" wide 14.75" high13.250 deep the port is"T" shaped it turns to the left and right at the rear the wall of it is 8.125 long and 3" wide, and 14.75 high those port dimensions are inside dimensions ans the box is built out of 3/4 in mdf

Thanks in advance for any help

i calculated 41 hz, which sounds about right for a prefab
