Heres the rest of the studio build.
Didn't cover the no rez installation because its pretty hard to mess up. Just measure out the shapes you need to cover as much surface area in the speaker as possible. It helps to draw out all the cuts you need on the sheet before cutting the minimize waste.
I put the crossover in with the large inductor towards the back. Gets a bunch of CA glue underneath and four small screws to secure it.

Then run the wires to the tube connectors out the back. It's very important to install them this way or else you'll wreck your hands with a soldering iron trying to reach them through the front of the speaker.

Once they are soldered on i use a soft plastic mallet to hammer them in. It's a very tight fit so make sure they are seated straight before you start wacking them.

Next up is installing the tweeter. I find it helpful to not install no rez in this area until after the tweeter is installed, not a lot of room to work here.
Using a 3/16 drill bit, eyeball a hole behind the tweeter to run the wires through. I strip the wire about 1 1/2in back and run the bare wire through the hole on at a time. You'll really have to pull hard to get the second wire through buts its better then having to refill the hole if you made it too big.

The Tweeter in these gets hooked reversed so white wire to + terminal and red wire to - terminal.

Fill the inside with as much insulation as you can fit without it touching the woofer. Doesn't need to be compressed and stuffed tight.

Woofer gets wired up.

After that everything should be done.
