Does the coupled value change with voltage or is it a constant?
I will need to stack a couple of inductors for the bottom end of my three way as well.
Don’t know. I’m using a DATS V2 to make the measurement, so I’m stuck with the fixed, small test voltage that DATS V2 is using. Can DATS LA vary the test voltage?
Also, I was thinking about setting up a breadboard type testing station on my bench using a function generator/power amp/o-scope/inductor/dummy load/distortion analyzer, etc., and then testing this for myself. I would test for both distortion and loss of in/out voltage at various low frequencies and power levels. But I am running out of time and need to button these speakers up for Indy. Maybe after Indy.
Can you use your two-channel measurement rig (Magic Box of Wonders version) and REW to measure inductance?
Yes, I could set up a simple loopback test and measure with either ARTA, REW or SE. EDIT:
And I should be able to vary the testing power level so that I can see how much the inductor’s distortion or value changes. Right now, I’m in the process of setting up a laptop/REW workstation on my test bench to test amplfiers and preamps. It will be a simply matter to test a single inductor (or multiples in a stacked series). But that is not set up quite yet. In the meantime, I’m lazy, so I usually just grab my DATS V2 to measure inductors.
