Actually the port would have to be 41.75" long to make up for the port end correction factor. If not the sub will see the rest of the wall (from the end of the port to the corner of the box) as part of the port. The correction factor is found by dividing the height of the port in half and adding it to the lenght: 37 x (9.5 / 2) = 41.75. Also remember when measuring the port to measure down the center of it.

Lv = [(14630000 x R^2) / (Fb^2 x Vb)] - 1.463R
*Vb = vol. in cu"
**R = sq.rt. A / Pi (for square/slot port)
