[QUOTE="Jimi77, post: 8856003, member: 673702"] Rigidity does depend on panel size, but ported enclosures tend to be 2x as big as their sealed counterparts, so we end up with bigger panels. Even if you design the baffle to be the same size as a sealed enclosure, you still have considerably more pressure inside a ported enclosure. The pressure inside the enclosure does not escape thru the port because the column of air in the port is out of phase with the sub and acts as another piston. If the pressure simply escaped thru the port, you would end up with cancellation. Pressure within a ported enclosure is greater than sealed just like pressure (measured in SPL) is greater outside the enclosure. [/QUOTE]
