Reverse Engineer a speaker crossover

I'm interested in building a portable bluetooth boombox, but I don't really know anything about audio. I am going to follow this forum (http://techtalk.parts-express.com/forum/speaker-project-gallery/62234-1st-boombox-project-the-madeleine?242898-1st-Boombox-Project-The-Madeleine=) for the build, which I can easily follow except for one part.

The guide gets kind of vague when he starts to talk about the audio crossover design, but there are some pictures he includes of the PCB and parts.

PCB assembled

My question is: Is my below (very crude) schematic correct? The connections in red are directly from the first picture of the physical PCB, but the blue connections are what I'm unsure of.

If you need any additional information like speaker frequencies or PCB component values please let me know. Thank you.
