Dali Zensor 1 - Reverse Engineer a Crossover?

Tolerance in components is hardly distinguable, I guess. 10 or 20 % won't bring dramatic changes 🙄

My experience is to the contrary, an old 3 way design I had could hold imaging as well as anything I'd heard, but fell on it's face when component values were out a little (an audible shift in apparent stereo image)

Replacing the components in the crossover and measuring transfer functions to ensure identical resulted in a massive improvement in performance, using solens as caps.

If you think a 10% variation in filter network makes littke difference, can I assume the design is only to within 10% of optimal and therefore sloppy?
 
While I wait for my LC Meter to arrive from China...

Are there any existing Dali Zensor 1 owners that can measure the L1 crossover value to help complete the schematic? That is the only remaining component that we are missing. Thank you! 🙂
