Effect of speaker impedance on 2nd order filters.

Because the mid-range HP and LP filters are 2nd order, the impedance of the driver is irrelevant. The fc of a 2nd order filter is 1/(2*pi*L*C) and the impedance is not a factor. This is not true for odd order filters. Use the spreadsheet and plug in different values for the speaker impedance and you will see what I mean. The Q factor is affected as Q=R*sqrt(C/L).
