That driver in a teeny sealed box will have it's Fc pushed way up: if the Qts is tripled to get a Qtc of .75, the Fs is also tripled to get a Fc of 63Hz.

The ported cab will have more bass. It would probably be shelved down a little compared to the midbass, but extension to 25Hz "beats" extension to 63Hz. Since the driver is the same, the efficiency is the same ...which means you have to "pay for" that extra low end extension with extra enclosure size.
