confused with Pete S.'s crossover diagram, help!

[sqkev]

The inductors for the da175 woofers looks to have 3 values,
.5mh with .7dcr, another .5mh with .1dcr and another 5mh with .24dcr

i can't seem to find those values on either partsexpress or madisound
are those values correct?

the .2mh inductor couldn't be found either

i'll attach the diagram

The 5 mH .24 DCR would be this critter;

As for the others - As Close As Possible - would be good enough.
Reason is the tolerance per piece if measured with a great meter will reveal that each piece will have a different value. Even with a plus/minus of 1%.

I twisted many of Pete's crossovers without having the correct part and they still worked. If measured with a good mike and speaker design software they might reveal a dip or rise of a 1/2 db. Clearly inaudible.
Oh and that parallel inductor - .2mH I'd use a .29 dcr. That one probably has little effect on the frequency response.

HTH...

The usual rule 'o thumb is within 10%, but the Jantzen .2mH is part # 255-210. #255-036 is pretty close to the recommended dcr and 255-408 is close to .5mH and has low dcr. These will be ok if the XO calls for different dcr's for the coils. The diagram is too small for me to read, but those values will work.

sorry about that
i never attached a picture so didn't know it came out that small

here's a bigger picture of it
