If you're after a sweet daily hit 33 or 34 hz. Have built many boxes for these subs, I have two in 3 cubes at 30Hz at the moment. Surprisingly louder at 35Hz, but surprisingly better sounding at 30. Built one for my mate that would have been around 33Hz for the same subs, and it was right on the money. And for that sized box do around 40sq. inches of port.
