In addition to the PS220 correction circuit design example, here is a comparation of two different results. The first one is from the YT demo (Link). It has two coils, two capacitors and it fits within c.a. +-3.5dB tollerance margin. The second one was designed with loosening part reduction strength, it has four capacitors, four coils but it is only a fraction of dB out of the target spl. The question if such a precise circuit is worth implementing remains open. However it's possible to design it with XMachina.
