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,

Hew,

Not observable and seamless mean the same thing to me. I aim for a soundstage in which the listener is unaware of any speaker, just fine imaging within the soundstage.

I think of it mostly as an HT phenomenon associated with explosions, etc. where you actually feel a pressure wave. A related but different phenomenon occurs with low pedal notes of a pipe organ, where you may feel more than hear them, just as at an organ recital.

I use a pair of Velodyne HGS-15s with an SMS-1. I set the levesl so the subs are not observable sources of sound.
