Hopefully I will have a bit of time making sawdust this weekend, plan is to build the second high horn cabinet, midhorn cabinet and hopefully vent's and bracing of a bottom.
But I'm unsure if the vent is supposed to be closer to the center of the room or closer to the sidewall of the room?

I'm having a issue with my crossovers. Lows and highs outputs are playing, but nothing at all from mid. Midhorn makes sound if I Connect to low/high output. None of the drivers makes any sound at all if I Connect them to mid output.
Strangely enough it's the same with both crossovers.
What am I doing wrong? Can you guide me through finding the flaw? Shipping Price is insane so I would like avoiding sending them to you.

It's definitely odd that both act the same way.
But regardless, let's just step through the troubleshooting procedure. Using an ohmmeter, measure across the following terminals and report back what you see:
1. Measure from IN- to 2- and find zero ohms.
2. Measure from IN+ to 2+ and find 4.5 ohms.
3. Measure from 2+ to 2- and find 8 ohms.

I'll be honest, I expected to see IN+ to 2+ as open if there's no sound. The fact that it shows continuity makes me think you should hear the midhorn. But another thing that could kill output would be a short across C4. You might measure across that component and report back.
Dumb question, but have you tried simply checking the wiring to the midhorns?
My 'go-to' is a regular 1.5V battery. Pull the midhorn leads from the crossover
and stick the wires on each end of a battery. It should make noise as you
connect/disconnect. You can also check polarity my touching the cone.
The crossover electronics aren't all that complicated, so I expect you can resolve
this without shipping. It will just take some back and forth and maybe
schematic reading verses physical layout training.
