L8 -- 0.5 mH inductor has to be .49 ohm correct?
This re-occurred to me when I was using the Bagby Passive cross-over designer
I have lots of .5 mH inductors; but the smalled gauge ones tend not to be labelled
I can't find any 20 gauge labelled inductors

I couldn't model midrange cross-over on this designer
The woofer zobel helped, but 65-80 uF zobel cap does not model well, I think

What about the resistance of the speaker wires? Or the wiring in the speaker? Or the amplifier output impedance? If 0.49 ohms is correct, what sort of tolerance have you got? I model my crossovers with a range of inductor resistance values to make sure it doesn't cause variation.

Any one know how these vintage rifa caps sound?
I believe they are metalized paper
Pic is of the tweeter section
Oops it has the wrong caps (0.1uF); suppose to be 0.01uF but I won't use those anyway probably

Guess I will listen to them, but I'm not sure I have a golden ear

Turns out I have a 19 gauge or .91 mm diameter .5 mH inductor and a 14-16 gauge also I think

Hold them to your ear. I'm pretty sure they're as silent as any other capacitors.
