There are a few here who can do some hand-holding.
Edit: I've also seen the opposite: constructors making bad choices through being uninformed, and then getting turned off DIY as a result.

With a good set of measurements the tools these days are so easy that one can easily play around. Ported woofer and a well behaved (likely sealed) mid enclosure. I would guess to keep it simple low order woofer/mid filters and something more attentive on the hf side of things (return on effort and smaller=cheaper components). The Hivi K1 and SD1.1 tweeters in my experience do well with 3rd order electrical filters and the cost of an additional cap won't break the bank.

Iíve been reading up a bit about crossovers on this website:

http://education.lenardaudio.com/en/06_x-over.html

.....

Our ears are most sensitive to detail between 300Hz to 3kHz.   The telephone system operates between these 2 points.   Sound system distortion between these points can easily be heard and therefore the worst position to cross speakers over, but we have no choice.   The best crossover points for our ears do not line up with the physics of speakers.   For domestic use at low power crossing tweeters over between 2kHz - 3kHz is often done in 2 way systems.   However the tweeter is easily destroyed at higher power particularly when having parties.   There has been many attempts to force speakers to be crossed over at 300Hz and 3kHz at higher power but with limited success.

It sounds like the guy is against crossing the drivers at 300/3000, but then again only at high power. What is considered high power in this case?

The implementation matters more than the specific crossover frequency. The frequency itself is far less important than other factors.

I would just like to one day sit down with someone who knows about these things, have a few coffees and a lot of sigarettes, and then maybe Iíll understand better

if you plan on making this a hobby start here

https://bit.ly/2HLF5KR

and you can use this software

https://bit.ly/2lb92vb

with this you will get a very good understanding and of what does what because you can now experiment and try different combination and track your progress
you will also find out how various combinations change the sound from musical to "choked" to death

I had a squiz at that web site. The generalisations there can be misleading. Read this, rather: http://techtalk.parts-express.com/forum/tech-talk-forum/38661-the-speaker-building-bible.

I'm definitely no expert, but it seems to me that none of those drivers are very flat from around 400 - 1500 Hz - shouldn't you consider a different mid?

one thing i realised
flat isn't necessarily a prerequisite. i am working with some drivers atm that aren't flat but they sound incredibly good
