What is meant by subwoofer room pressurization?


I've recently been researching some subwoofers and people frequently mention the fact that they pressurize the room, supposedly resulting in better sound, not just better bass. Could somebody please explain this to me? I've searched other threads, but to no avail.

Thanks in advance,

Some say that when a wave is unable to unfold that it 'feeds back' on itself. Thus pressurising the rooms' volumn. I think the frequency is about 150 hz for a big room to 350 hz for a small room.
