Default My 6th order design

So, I am mostly a lurker and have been reading up on 6ths for a while and think I actually might have a design that'll work. The thread that was really helpful was one over on caco (idk if I'm allowed to post the link here. I will if I'm allowed) but here's a summary of what I've learned:

Inner box- generally to ported specs (volume), ~3-5sq in port per foot, tuned low (aeros work well to keep port noise down)
Outer - volume depends on ratio wanted - 1:1 fairly flat between tuning points, 1:2(inneruter) peak near higher tuning point, 2:1 peak near low tuning point. Port - 35-50sq in port per foot, tuned one octave higher than inner box (one octave higher is double the one below it - ex: 60 is one octave above 30hz)

general rule of thumb: don't have ports firing into each other. inner ports need to be able to load off a wall

If there's anything I missed, please correct me


My design:
Inner-


Outer-


Cutaway -


Finished box -


Sorry for bad sketch ups, I'm still new to it
