Well I see a pole at about 60Hz from C1 and R2, and the 0.5Hz pole from the servo, Not sure about the zero (from L1 / R6, should be 6Hz or so but seems to be lower, but it will be interacting with the nearby poles).
To pass 20Hz I think C1 should be more like 2µ2?

Thank you, Mark. The circuit is supposed to drive a sealed box midbass, crossover 60Hz. The reason for DC coupling is to control the cone below crossover. Interesting point about L1, haven’t given that a thought. Ie another parameter to include if wanting to cross lower.
My main interest is to find out about the relationship of current and voltage at the output of the servo.
