Neophyte that I am, I found the exercise with that simple circuit illuminating. Below 10 Hz, it's just the DCR of the coil in parallel with the resistors, basically.
Above 1 kHz, where the coil has gone high impedance, only the resistors remain in play.
Fun stuff, this.
Why it was deemed appropriate to let the HF pass at all in Citation 7.4 remains a mystery to me. Perhaps it's an artifact of another design objective there.
[It certainly messed up my woofer tests for a while, tho.... ]
