Spelling correction, it's Jäger. Umlauts are very important with camlock construction.

I'm not a linguist, but typically umlauts are consistent with Germanic languages :

You mean, like German…?
The language that the word "jäger" comes from?
That kind of Germanic?

Or Swedish as in IKEA the masters of camlocks?

Lol. Just in case you were wondering which end was up

Quick update - we are making good progress with the manual photo shoot. I want to mention that this is the easy step. Josh still has the big job of the accompanying written instructions, and that will take some time. While he is doing that, I will be getting some final measurements and taking product shots. We are also exploring custom packaging for shipping the cabinet panels. We hope to be ready to begin taking orders very soon.
The first few cabinets I assembled were hurriedly finished with Tru-Oil, as I was mostly concerned with getting them running. This latest Baltic Birch ply cabinet for the manual build received a sanding with 220 grit paper, two coats of Seafin Teak Oil and a finish sanding with 400 grit and a buffing with a cloth this morning. It took about 20 minutes and the surface feels very smooth, with a nice satin finish.

OK, here's pretty much what the production Jäger speaker will look like. Slightly different felt colors than the previous iteration, and you can see how the passive crossover installs and connects on the back side. The passive crossover down in the rear cubby can be run with a single amp, or with two amps for biamping by removing a jumper. Down the road there will be an active tube crossover kit that will allow biamping without the passive crossover. In that case the passive can be pulled out and tweeter and woofer speaker cables will connect directly to the upper binding posts.
Apologies for the soft images. It would seem the Wordpress photo editing tool is from 1996. Next time I will size them in Pshop. Also a reminder that a pair of these will be running with Kaiju monoblocks at Bottleheadquarters tomorrow from 12-3.

Nice and tidy!

Looks great! Did I miss the dimensions? I'm curious how tall these are.
Crossover is around 3200Hz, IIRC. All the specs will be up on the website in a few days. You cannot use separate binding posts for each woofer without changing internal wiring. The woofers are in a series wired shaded array configuration and getting it all into balance with different wiring and amps could be rather challenging. This is intended to be a pretty fully evolved design that includes very specific components to achieve its performance rather than the typical drivers, capacitors and binding posts speaker "kits" that so many companies sell. The many months it has taken to get the design to this point have been spent trying a lot of different circuits, materials, etc. I know it's fun to embellish this kind of thing with our own musings, but I would hope that builders will give the design a chance as delivered before personalizing it. That way one will have a baseline from which to determine whether any mods are a step forward or not.
With regards to using lots of amps, some may recall that a main point of this exercise was that the guys wanted me to put a speaker in our studio that would work with a single amp of modest power. I will be doing a little demo of the capabilities today, as we run the 94dB speakers with 16 watts per channel. That's 106dB peaks.

Wish I were in the area! It would be great to hear these.
While the tweeter is a bit more sensitive than the woofers, we took that as an opportunity to flatten out the tweeter response a bit.xcortes said:

The acoustical crossover is at 2800Hz.
