ported box for 2 10 RF Punch HX2 subs

Ok so I'm looking to build a ported box for 2 10" RF Punch HX2 subs. I used a program to figure out what all the details, this is what i came up with. Vb 3.89 Cu/Ft F3 22.51 i can't see where it gives me port area, but it i have Height, Width and Length Height 13.5" Width 4" Length 43.31" I have a JBL 600W Mono amp i'm going to be using, i figured that in also. The box is supposed to be high output while still keeping a little bit of SQ. Here is a picture of the box modeled. That mesurment thats hard to see is 1' 9 13/16"

Err well i guess for some reason the topic title got mangled. Anyway what am asking is that maybe a person more with more knowledge about box building could check my work.
