“Tight” bass no. But efficiency and box size have a relationship for deep bass. The pressure increases faster in a smaller box and the driver has to work harder to overcome it.
I think when many people refer to “tight” bass they are trying to express a juxtaposition to the perhaps more common “loose bass”. A sealed box will often provide tighter bass than a ported box, but if comparable bass output is to be achieved, the sealed box will typically do it with less efficiency.
In general, low bass extension comes at a cost and that is Sensitivity. This is only a generalization, overall, the balance of mass vs motor tells the story, but regardless of the woofer, anytime that you add mass, FS goes down and so does Sensitivity.
