no need for ported boxes. buy the right sub, feed it the right amount of power and put it in the right sealed box to get the performance youre looking for

Informative discussion on the topic.

The person I quoted claimed you only gain 3db if you double cone area AND power and that there was no gain for just doubling cone area. The thread you posted seems to be correct as well.
