Help with 4Pi box (newbie questions)

Hi everyone

I'm starting to build a pair of 4Pi for my 300B DIY amplifier (my current 88db speakers are not tube friendly at all)

Unfortunately, I'm a complete newbie to speakers and it's likely that the guy who will actually build the boxes is a wood worker, without any knowledge about speakers.

I have the 4Pi plans, but since I have never built a speaker box before, a lot of questions arise about the internal structure.

please please, would anyone post a picture of the cabinet's internal structure? I have searched through the forum, but most of the pictures are kind of 'expired'

I'm mainly interested in the horn and port area.
is the tweeter tied to anything? is it just attached to the horn?
The port is made of the same material as the box? is there any space between the port and the closest side of the cabinet? or does the port starts where the cabinet side ends?

A simple picture would solve this questions

Thanks in advance!
