Help matching inductor values audax center channel

[drovn]

First post, just signed up and searched for some clues before posting this problem.

Trying to duplicate Audax's center channel. My problem is the inductor values shown in the original plan. Madisound's Audax center plan shows different inductors/values while keeping the capacitors and resistors the same as the Audax original. Is it ok to substitute like the example below?

Audax : 2.7 mH 16 AWG 0.53 ohms
Madisound: 2.75 mH 19 AWG 1.05 ohms

Audax: Erse iron core inductor 6.8 mH 0.48 Ohm .
Madisound: Their Brand iron core 7.0 18 AWG 1.2 Ohm


Are these acceptable/ interchangable?


Thanks a lot for any help.

I would be a bit worried about the DCR being pretty high.

I would give madisound a call and see what they suggest. I'm sure they must have a good replacement in mind since they host the design plans.

You also could try searching on the madisound forum.

HI the differences are so minor as to make no real difference to the performance of the unit, IMO madisound changed them to fit in with inductors they have in stock... thats all I'm sure they will confirm this for you cheers TC

I just ordered my parts from Madisound a couple of weeks ago and I used parts from the sale page for the 2 coils in question. I believe you would be degrading the performance a bit with your substitution of an 18AWG coil in series with the woofers.

Thanks for the replies,

I'm basically just trying to figure this out:
If I'm following someone's plan and I pick a coil with the same mH value, I really should shoot for the lowest DCR like a 12 or 14ga aircore and not worry about what the original plan had specified?

Thanks again, good forum and if anyone has a good center channel plan, please let me know.
