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?

A ' driver ' has electro - mechanical - acoustic properties ( TS Parameters ) and the volume relates to ' efficiency ' in a ' system ' ( loudspeaker ) as well as other relational properties.

It's a shame manufacturers went the way of small thin cabinets and tiny woofers. They all sound like giant tweeters these days....
