There is no free lunch on the port size. Passive radiators will not cause cancellation if done correctly, but they would most likely need to be mounted on the side opposite the woofer. Just cave in and go sealed box at this point, it's the most expedient option. Fool with the ports later.
I'd like to know what the Qts of that woof is.
