How do I determine the electrical value of an air core inductor?

I've got an old set of speakers that I want to update. The crossovers contain inductors, but I don't know what to order to replace them. I'm assuming that copper foil inductors would help the SQ, but I don't really know. I'm just doing it for fun to see if it helps the SQ. I've already updated the caps and wires, but was stumped when it came to the inductors. So far, the changes have been positive.

I've checked the manufacturer's site, but they have no info on the speakers they manufactured so long ago.

So, how do I find the value of the inductors? Would a DMM help?

You need an LCR meter.  It measures inductance,capacitance and resistance. See link below

Thanks, Scotty. I was afraid of that... spend more money. Well, what's a hobby for?   :lol:

Caps, braces, and deadening materials will usually make a much bigger difference than inductors.

S Clark,I agree with your statement but after you have done the aforementioned, the inductors are worth doing, especially in a two-way loudspeaker with a crossover in the midrange.

S Clark, after looking at Candace's speakers, I am inspired to give some attention to sound absorption in the cabs.

Scotty, it happens these are two-ways, so your point is well taken.

This is great! I'm always learning something new. Thanks.
