As rego mentioned: how a driver responds in an enclosure, depends largely on T/S parameters.
I didn’t notice anyone else providing further info, but- I HATE to type, so:

Physics Question: Why does cabinet volume matter so much to bass response?
If you put the same 8' woofer into a bookshelf speaker or a floorstander, you will get a different frequency response. Does anyone know what's happening with the air pressure on the inside of the cabinet to cause this to happen? Does the woofer in the bigger cabinet have greater excursion, and therefore produce more amplitude?
