Inductor Choice

I want to use Jantzen air core inductor for the tweeter, copper foil inductor for the midrange and Jantzen iron core with disc for the bass.

What I concerned about the crossover is set at 400Hz, and any conflict by using different type of inductor (copper foil and iron core with disc)

Thanks 🙏
 
The stock iron core inductor for tweeter has 4.5R DCR, and I'll replace it with Jantzen air coil with dcr 2.24R and put a 2.2 resistor in series to achieve closer to 4.5R

The copper foil inductor has DCR with 0.54R vs the stock one that has 0.6R

The iron core inductor for the bass has the same DCR as the stock one, which is also 0.45R

While inductors for the mid and tweeter just got influence on the spl, the inductor for the bass increases your Qt, so you have to include it in the tuning of your speakers. Enter it in the simulation and change the enclosure volume (it needs to be bigger).

Why both tweeter and mid influence on the spl?

If the mid uses the same type of iron core use on the bass, shouldn't it any problems?

Every serial resistance is reducing the spl. But on the woofer it changes the Qt too. Why not for the mid and tweeter? Unlike the woofer, they aren't used at their resonance frequency.

To use iron core coils above the bass is much more expensive and air core coils have lower distortion. It is reasonable to use them there. In the bass range the iron core makes often sense because a big air coil will have higher Rdc or needs a much thicker wire, which makes it more expensive.
