Assistance with Reverse Engineering Crossover

It might be possible.
An experienced designer will probably see what topology is used and can figure out the most likely configuration.
Lets give it a shot...

If its a current model of a commercial loudspeaker I would avoid helping you so please let us know what speaker it is.

If I see right it is configured like this picture. Sorry for the quality.
12dB low pass filter with a kind of shelf filter which probably are a baffle step compensation. Woofer connected in phase.
24dB high pass filter for tweeter with a lift in the highest treble. Tweeter connected with inverted phase compared to woofer.
I have set out the values I can see, so fill in the rest when you know them.

Sorry, but there are no miracles to be found in this configuration and it can't be used with other drivers.
It's past midnight here where I live so my brain is not the quickest right now, so hopefully I haven't made any mistakes 🙂
