It was very nice of you to do the design. Not trying to be rude but the port length is actually measured as 27.25" (you measure down the center of the port and add 1/2*width for "end correction"). It will lower the tuning (probably around 30hz) but its not a really big deal.
That was very generous of you. I dont want to sound like a d*** but i actually have two and im getting one fixed (broken tensil lead). Do you think you could play around with a design for two 12"s? Same freq. just double the volume. If you could that would be awesome. Thanks again man!

I got 27.25" of port at 3.36 cf net. If the net displacement is 3.2 assuming 0.16 for the sub, it should tune to 29 hz.
Port should be 22" long.

****, just realized i measured the port wrong. Knock 1.5" of the second panel of the port to fix it. So it should be 5.75x 13.

Measure down the line through the center of the port, adding 1/2*port width at the end if using the wall of the box as a side of the port.
Lol i missed your little post above. WiniSD said that i needed 22" of port to tune to 34 htz. Also thanks for correcting me and for the 1/2" tip.
OP im working on the design for both now, ill PM you when finished.

You need to have at least 40 sq of port.....50 if you like it low and loud.
