WTK- where to get Crossover parts...

Postby NateM92 » June 16th, 2020, 1:05 pm

Looking for 0.3mH Inductor Coil and 10uF Capacitor... a lot of places have only Capacitors no inductor.
Anyone know where I can get it?

Check sham's and steves

But inductors is just a coil of wire eh, you can probably make that from scratch. Here is a calculator to get you started:

But read this first:

You can get the coil winding wire in sham's and steve's as well.

It would help a lot to have a multimeter with a mH setting as well. But you can go even more extreme DIY with a program called ARTA, you'll need to build a test jig.

So no iron core, it's just a coil of wire ?

Yup in most xovers designs air core is used.

is there any advantage/drawback, db slope change, inductance change, between metal to air core?

As for slope, that will depend on the order of the xover network you construct.
I read something once about ferrite cores causing distortion due to hysteresis or something at higher power applications. I'm not too sure of the specifics, however, good hifi systems only employ air core inductors.
I guess you can google that up if you need to know more.
