Hi,
For speaker crossover design requirement is DCR matching mandatory (zaphaudio SB12.3)
4 mH DCR - 0.21
Locally I have found 4.0 mH / 16 AWG but DCR is 0.282 Ohm
Does 0.21 vs 0.282 makes any difference. Can I go with 0.282 Ohm without having any impact to design/sound.
Thank you

Small difference compared to driver DCR so should change little.
I would use them with no reservations.

What about Inductance.
Design requirement - 1mH
Inductor wound by hand Actual - 1100uH
Does 1.0 vs 1.1 matter?

LCR meter reading is not consistent, so wanted to know how much difference is easily acceptable.

It depends, for a complex crossover or one with steep slopes then .1 mh difference can be suboptimal, but for a simple crossover or one with shallow slopes then you might not notice any difference
That's right, notch filters tend to be critical but for ordinary low pass you can get away with small variations.
Unfortunately the 1mH coil belongs to a LCR trap, you're better at provide the right value.
