I would actually expect to see your box with no higher than 30Hz Fb. Would be interesting to see an actual impedance sweep of your box.
I'm using hornresp and winisd. If I get around to it in the next day or so, I can pull up the models and double check the numbers.

Too long ports might have their first port resonance in the band you want to use them.
I aim at a 1st port resonance of at least double the highest frequency I want to use the sub.
So if a sub has to do 18hz - 80hz, I design the first port reonance to be at least 160hz.
