1st order - means the crossover has a 6db roll off and a 90 degree phase shift.
2nd order - 12db roll off and a 180 degree phase shift
3rd order - 18db roll off and a 270 degree phase shift.
4th order - 24db roll off and a 360 degree phase shift.
I believe I remembered correctly. Someone please correct me if I'm wrong.
