OK, mate. Let's have a look at this.

The dome and tweeter layout makes sense. It effectively makes a giant tweeter that crosses over at about 1kHz.

I can't make much sense of the left hand woofer with the simple coil. I presume it's the bottom driver with some natural rolloff around 500Hz, but I really don't know. The markings are curious. M seems to say midrange, but that makes no sense. The B section with a coil and 22uF capacitor connected to the top woofer in its own little enclosure should cross over to the dome and tweeter reasonably well at about 1kHz.

I'm guessing on the coil values, by the way. TBH, this is an odd design. I must be missing some essential feature. I would expect the bottom woofer to have a 50uF capacitor or similar.
