Default How Close Can My Tweeter Be?

I'm working on a coaxial type contraption.

When I get the tweeter close to the woofer, I can "feel" the magnetic field pushing the tweeter away.


What's the effect of putting them very close?

I know that in crossovers, we're supposed to arrange our inductors at right angles to prevent this from happening.

Is the same true of speakers?

Also, would using neodymium for both drivers help this? Currently I am using a neo midbass and a ferrite tweeter.

I have a 3D printer, and if possible, I'd like to put the tweeter just millimeters from the cone of the woofer.

interacting dynamic driver motor mag field leakage is unlikely to change gap B, BL force products by meaningful amounts for practical geometries

air gaps give very high "magnetic circuit" reluctance, scaling factors of sq or cube re voice coil gaps

I'd try running an impedance sweep for T/S parameters with and with out the tweeter held where it's gonna be and see how much it effected those parameters .
