Thanks for this thought.
The tweeters already have doubled - very strong - magnets, stock from the factory.
In any event, the low-volume tweeters have been sorted and I am now just wrestling with converting the physical crossover to schematic.
...Far more challenging than I imagined! 😊

Many thanks for highlighting the errors in my earlier crossover schematic... Devilishly tricky stuff, to be sure! 😵
I've stepped through it again and moved some things about - hopefully correct this time.
If you more experienced veterans can spare a moment, please let me know if anything looks wrong. Appreciated.

My advice. Break it down to three x-overs. Then logically ask what each filter would likely be needed to do.
Tweeter. You show a damped 2nd order with no padding. Could be. Could it instead be a traditional 2nd order with a single resistor to pad down the tweeter. (ie R5 would be in series with the fuse. )
The woofer part seems reasonable.
Mid. It's currently wrong.
Do you have measuring gear?

Very good advice. Many thanks. 😊
The measuring gear I have includes a FLUKE 12E+ Digital Multimeter and a VICTOR 6013 Digital Capacitance Meter. I'm presently exploring Digital Inductance Meters and will grab one soon. Sadly, no scope.
TWEETER:
The crossover board shows that the FUSE can "see" both R5 and C3 directly, so I think this section correctly reflects the factory crossover. I invite alternative schema suggestions.
MID:
The MID circuit has been a real challenge for this crossover novice. I think I have worked it out, reflected in the new MID schema below. Again, I invite alternative circuit suggestions that reflect the factory crossover shown.
BASS:
I agree that this is probably the simplest circuit of the three. I think the above schema correctly reflects the factory crossover.

Many thanks for sticking with me on this.
I'm not disagreeing with your last comment, "with R2 where you show it, the mid would be virtually silent."
That aside, would you agree, that based upon what we see on the crossover pictured above, that the schema I have produced above accurately reflects what we see?
Or is there another configuration that has eluded me?
As I say - I ask this question, ignoring the fact that your last comment may well be correct...

maybe R2 is 6.8 ohm, not 68ohm
if its written
R68 its 0.68 ohm
if its 6R8 its 6.8 ohm
if its 68R its 68 ohm
is that correct?

I have updated the previously errant value of R2, below.
(Thank you, @Freedom666!)
Once I purchase a Digital Inductance Meter, I will update the values of L1 and L2.
