This is as far as I got before being shutdown by the kid:
So far so good, the tweeter is no Viawave, and isn't even as good as the round faceplate GRS but it works just fine.
The woofer is a champ. Extremely good, better than the paper version I have used a couple times. The only drawback is it requires a relatively large cabinet to take advantage of its low Fs. I am at ~0.57 cubic feet for an F3 of 40Hz.
If I am allowed, I will post the individual driver rolloffs. This iteration has the crossover at around 3.9K

Thanks for the inspiration - I am going to name these the "Exclamations".
OK, they are 2nd order slopes resulting in a wide but somewhat shallow reverse null (forgot to save a pic) which is where the phase fuckery at 7K presents itself.
Here it shows individual slopes based on modeling. There are a few component differences, plus I added a notch on the tweeter at 1500Hz in the model because it just looks better on the bottom end.
So made a few changes, and ended up with nice, almost textbook BW3 slopes. Barely any change when reversing polarity on tweeter. Sounds decent enough, but does lack a bit of sizzle on the top end. On the other hand, sibilance is very well controlled. Distortion is manageable, as well. I will post final measurements in a few days.

The dip ar 7K is a phase issue I am debating on chasing down.

I believe Curt and Wayne had a speaker design they named the Exclamations.

Don't be a stahl head!
I'll just come up with something else, then. No worries - not going to stahl a name.

I may wire this up and give it a listen later.

I've gotta turn this pile of shit into a couple crossovers. Sigh. Just lazy I guess.
I'm sure your orange cylindrical supervisor in the background is keeping you on task.
