substituting 4ohm for 8ohm midbass driver

[sreten]

Hi all,

say I want to replace an 8 ohm midbass driver with a nigh
on identical unit but it has 4 ohm nominal impedance.

I have the crossover details for the 8 ohm unit. I don't think
I should simply scale the crossover parts to 4 ohm because
isn't the real issue the inductance of the drivers ?

So my question is : what would be the typical difference in
inductance of 8 and 4 ohm versions of the same driver ?

(no sensistivity issues as the tweeter has an L-pad)

You will need to modify the x-over to suit the 4 ohm impedance, the inductance of the driver does play a role but it's not primary one.

I would assume the 4 ohm version would have a lower inductance all else being equal.
