I’m upgrading my crossovers in some old Klipsch speakers
One inductor needs to be 2.5mH
What I have are some 1.5mH and 1.0mH
These are Flat copper foil inductors
I found a way of hooking and lining them up in a way to get the 2.5mH that’s needed
I know with caps you can do this, but is this ok with inductors ?
One will lay flat and the other ( smaller ) will be sitting on top of the flat one, right in the open hole of the larger coil
I’ve tested these with 3 different lcr meters and they all show the same readings of 2.5mH.
So any ideas of if this is ok or if it’s not ok, why ?
Thanks

Flip one of them over and see whether the reading stays the same. I'd expect them to interact. This is something that might be exploited in such a situation to reduce the resistance of the combination.
Kept far away from each other inductances will add like resistances, but if you overlap a pair of them you can get upto 4 times the inductance of a single inductor - for air-core it won't be 4 times as the leakage inductances will be substantial, reducing the mutual inductance. You'll be able to tune the inductance by adjusting the relative position.
