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.
My question is: Is my below 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.
UPDATE:
I've found a picture of the bottom after scouring online for a while. I've posted an updated schematic with what I think is accurate based on the pictures. Do you think this is indeed a correct schematic?

I checked your link, but stopped reading when I reached a picture of the bass reflex vents. They are way too long. Also the drivers look very expensive. But it will sound like crap because the vents are way too long, so they will resonate like organ pipes. This hints at the designer having no clue what he's doing.
I'd advise building the classic:
