inductor in series or not

[Tubenstein]

I see crossover circuit has two 1mH inductors with same inductance but different DCR wired in seriesvfor high pass filtering. What are the advantages?

Would one single 2mH inductor do a better job?

Best post the crossover circuit so we can be sure of the positions of the two inductors within it.

Let me prepare the circuit
