..or how I think it should have been represented in the DIY Audio link provided in my original/earlier post.

That schematic looks correct to me, based on the couple pairs of Minimus 7s I've modded. As I recall, the woofer is run full range with no crossover rolloff, and the tweeter has a 2 component high pass filter (cap and inductor).

...that you should connect one lead from the inductor (coil) to the positive input (red binding post). The other should be connected to the solder tab on the woofer that's marked as positive. One lead from the NON- polarized capacitor should also be connected to the positive input (red binding post) and the other lead connected to the positive terminal of the tweeter. Connect two wires to the black (negative) binding post. Connect one to the woofer negative tab and one to the tweeter's negative tab.
....it seems as though you might have got something wrong somewhere...nevertheless, appreciate your help indeed.
I believe the following may be correct...and is in line with attached pic.
--------------------------------------------------------------
Note : in attached pic, red input terminal on the left, black, right.
Inductor connects from black input to the solder post, far left, top.
Capacitor goes from red input termnal to solder post, which is also tweeter blue lead connecting to the tweeter brown terminal, presumably (+), though I don't see it is marked so.
Other tweeter lead, black wire to tweeter white terminal, connects to black input terminal.
If you're sticking with the original filter, use a 4.7 uF metallized polypropylene cap.
Woofer connects across the input terminals, yellow wire (+) to red, and black wire (-) to black.

...based on the the typical 2-way, 1st order electrical filter where the active elements are wired in series with their respective drivers..
