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,

I purchased two 15" subs. I first placed both them on either side of my equipment cabinet facing the audience. I was very disappointed in the impact, so I started reading the sub manual and tried different placement layouts. To get the pressurization effect you're talking about I placed one in the front facing the audience and the other at the back on the opposite side of the room. Now I have bass air pressure coming together right at the point of the seating.

It's a sonic boom... like night and day. The room has become a music chamber and the sound of explosions is unreal. The entire house shakes... the sound is better than a movie theatre.
