Just the thickness of the material. 18mm that is.
When I run those numbers I get a 61.33 hz tuning, not a 40 hz tuning.
I personally would suggest going 141L (5 cubic feet) with 2 12cm (4.75") ports 21cm (8.25") deep. That gives you a 40 hz tuning with a nice plus or minus .75 db shelf from 42 hz to 200 hz, about where you want a kick drum monitor in my opinion.
