[QUOTE="SlugButter, post: 8832381, member: 678073"] The “order” is describing the energy storage. its like a spring with a weight on the end (2 orders of stored energy), or a piston with a push/pull component. The coil(spring) is stored energy and the mass of the cone is stored energy, so a sub in a sealed box is a 2nd order (2 components of stored energy). Adding a port acts like adding a second “piston” with a push/pull effect, making it a 4th order. A PR is the same as a port essentially, having a spring and a mass(the cone) it adds 2 orders of energy storage, making a PR enclosure a 4th order. Adding 2 PRs to a single sub would make it a 6th order bass reflex enclosure, not to be confused with a 6th order bandpass enclosure. [/QUOTE]
