Hi everyone,
I'm confused....for woofer and tweeter impedances of 8ohms each and a common crossover freq of 2500 Hz,WinISD gives different values for L1,L2 and C1,C2 for a 2nd order network(L1=0.72mh,L2=0.36mh,C1=11.254mfd,C2=5.627mfd) whereas in other online calculators L1=L2 and C1=C2.Why is this and which one do I follow?
Thanks.

The online calculation results were for a Butterworth filter.
WinIsd calcs doesn't match any on my PCDC calculator program.

Although I can get the same values you got with WinIsd when my woofer is 4 ohms.
