Speaking of crossovers, would it be possible to add the HF compensation required for the JBL 244* series compression drivers to an electronic crossover?

I have a Marchand XM-9 with 24 dB slopes that I'd like to compare to the Pi crossover, but in its stock form it only has regular level controls for LF and HF, plus a "damping" adjustment to boost or attentuate the signal at the crossover point.

I also have lying around an old Audio Logic X22 crossover, which only has XLR inputs and outputs. This crossover has a "CD EQ" button. Is this equivalent to the HF compensation that the Pi crossover uses?

Thanks and best regards,

Joel.
