Sealed box for FI Q 15

[xxdadixx 0]

Hello, first of all please excuse my english, I am from Romania.

I just received a fi Q 15 ( no options ) and I am trying to calculate my speaker enclosure. I want to go for sealed enclosure because I don't have much space in the trunk ( BMM e46 sedan ).

Recommendations for fi q box is 2-2.6 cu ft. With my calculations I am about 2.5 but I want to be sure I calculate it right before I give the blueprints to the box builder

This is my result, I am happy because it fits inside the trunk perfectly. I made a dummy box to see how it will fit inside the car.

Wood is 1 inch thick.

After some quick math I came up with 2.47 cubes before displacement. Some polyfill and thinner material with bracing should do the job right
