assuming a "Zobel" network on a fullrange, is AJ-Horn good enough to get starting values for a notch filter?

-purchased one Gradient Acoustics AX08 8 inch fullrange. Like many, it will need contouring. Here's a Foobar EQ setting by one user. I'll be using LC &R parallel. The first coil I see laying around is 0.8mH/ 0.43 ohm

there's a filter shown on one website but with no values. IIRC, it used LC with no R, and a RCL impedance equalizer across the fullrange

I tried to write to the distributor but am not sure the email goes through after the inscrutable "captha"

I'll have to piddle with RTA and pink noise

build quality of the driver looks very good for the money

here's a set of published response curves - what value coil would you pick for the parallel notch filter?
