In all my reading about subwoofers, I've never seen a true definition of "pressurization" in any forum from a "technical" (yet accessible) standpoint. Every characterization has been of the "feeling" of pressurization. Surely there must be a ballpark formula to measure whether a measured subwoofer(s) will "pressurize" a given room volume (assuming it's sealed). I understand about the concept of wavelength wrapping back on itself depending upon room size, but since wavelengths are different at different hertz, I'm not sure I understand exactly which waves cause pressurization and what part SPL may play in this.
