Representing passive crossovers as a gain function

[yogurt21]

Is it possible to represent a given passive crossover design as a gain function, like one could do with an active crossover/EQ curve?
Assuming of course that we know the impedance curves of the driver that will be driven by it and there is no variation in the crossover component values.

In other words - if I were to simulate a crossover design in VituixCad with flat frequency responses, would the resulting individual driver curves be a simple product of driver frequency response (in this case: flat 80dB) and the crossover gain function; and then I could presumably derive the gain function itself by dividing these responses by the frequency response (or just 80dB in this case).

With the caveat that such a gain function is valid only for a driver with an identical gain response; this is not an issue for my purposes.

You can simulate a passive crossover's frequency response, effectively its gain across the frequency range, using appropriate software like VituixCAD.

Not sure what dividing by 80dB is supposed to accomplish in the example above.

What I would like to do is isolate the effect of the crossover on the drivers, hence dividing it by flat response.

I've decided to just try doing so based on the files available from Mechano23 - and the results mostly agree, except <0.5dB difference at 2.1kHz (and larger differences well beyond the crossover point):

My actual goal is to try and derive individual driver response from the spinorama data published in Amir's review of the speaker - but with the accuracy and resolution of the Klippel NFS, which is significantly beyond what can be achieved with quasi-anechoic measurements.

The remaining issue would be how to disaggregate the two responses from a single, combined response. Once I have that figured out, I should be able to generate a full set of 72 measurements for each driver of these.
