Inductors

To introduce the least possible attenuation, a good inductor must have a low DC resistance. In the case of series inductors (woofers) this is crucial!
The greater the section of the copper wire, the lower its resistance will be.

To avoid using too high diameters (and therefore excessive costs), ferromagnetic cores are used which, with the same turns, increase the value of the inductance.

The physical value that indicates this parameter is the Q or merit factor.

If an "air core" inductance does not involve risks of saturation,
an inductance on a high permeability core could alter the timbre: not always the highest Q is better!

The selfbonded wire in addition to the insulating varnish, has a surface thermolacquer: if heated to a predetermined temperature,
the turns are compacted to the advantage of mechanical stability.
