how do you measure the coil in the crossover?


I am in the process of tweeking my rather inexpensive speakers, and I want to update the crossover componants. I would appreciate any help someone could give me on finding the value of the inductor coil for the low pass filter. I want to buy the alpha core equivilant.
Thanks in advance!

you need to measure not only the inductance value but also the Q factor of the choke, which a simple DMM won't measure. An impedance bridge is required but that's simply cost prohibitive. You'll probably need to find an electronics lab to check it out.
