contray to what you told me in your email you really didnt have much room for this box after port, sub, and wood displacement. 11"s for depth really isnt much at all na when the cubic feet of a box gets smaller the port will be longer at lower hz...
best i could do to keep your desired tuning is 1.525 sq inches 35hz 33.25 sq inches of port area Im not really happy with this box design either, port area is really minimal and volume is just teribble and the magnet of the sub is to close to the port...ask your friend for more room.
