Are point 1 & 2 not contradictory?  Surely if the total AC impedance
of the inductor was not an issue as you claim in point 1 it would not
need to be considered as part of the design as you mention in point 2.

My experience with 3-way designs is that a large inductor of (say 6mH
and DCR = 0R8) has a very significant effect on the bass tuning.
Which agrees with point 2, but not point 1.

Hope you can clear this up for me.

Thanks in advance.
