Dear Anyone Kind who could model this for me,

custom designed Xover: Fc = approx 950Hz 18db/oct different sort of filter: LCL

So input parallel shunt inductor of 1.3mH into polyprop 42uf series cap into parallel shunt inductor of 1.3mH.

The input inductor has a 25 ohm resistor in series plus DCR of .6 ohm: ouput inductor also has a DCR of .6 ohm driving an Lpad driving an 8 ohm Selenium D210ti compression driver.

The result I am getting seems like way too low Fc, and high distortion. I have no test equipment or even test CD now.

I think the high inductor leg resistor is too high, but I don't know. I havedone the best I can to make this thing work.

I designed a similar style filter with excellent results at 5khz, however I had only a 4 ohm resistor in the input leg.

Any Modeling would be great.

Thanks Sincerely,
-3db
