Common air use

So I was wondering and im sure their are plenty of people here who have been around the block with different sub woofers, so i wanna know.
What sub woofers have you all come across with 3.0 cb.ft 4th order(Vented) box space and at what HZ tuning?

 

so.... not a single person has ever used one sub woofer that could use 3.0 cb.ft for a ported box?

 

ok than, so what sub woofers were they if you've had three and or three of the same kind if I understand what you were trying to say.
And whats the HZ tuning for them?
