In 2019 I had a local cabinet maker build me some Cornwall/Altec 19 inspired two ways from 3/4” baltic birch.
He even used baltic birch for bracing and at my request, we ended up making the motorboard 1.5” thick (2.25” where the t-nuts for the woofer mount) for no good reason.
These speakers have provided countless hours of crossover and driver experimentation. I have left them configured with 15PR400-4s and HF-146 on ZXPC horns.
They are crossed at 700HZ and sound very balanced. I’m sure a digital active crossover would have been much easier to work out but clearly I like old school stuff.
The crossover was by far the most frustrating part of working through this design and I don’t claim it’s perfect. They are very dynamic/efficient and more polite than my Cornwall IIs were but still posses a front and center presentation.
Alas I think I am ready to move to a smaller box for continued scientific experiments. These are 23.5x24x43.5” and guessing they are roughly 150 pounds each!
You can experiment to your heart’s content or leave them as they are. I am near Cedar Rapids Iowa.

That corner joint look awesome. To work with that router bit, a table router is needed right?

I liked that white paper above. One interesting bit was about measuring a change in the brain waves of subjects listening to super tweeters or not. A prime example of "not everything that can be measured (necessarily) matters..." On one level I think surely if my brainwaves change the difference is perceptible - I could tell...but....MAYBE not... HeHeHe.
One thing I do know is I like the sound of my UG Jubes with TAD 4002s driven by First Watt SIT2 up high and Hypex NC400 monoblocks down below. Looking forward to comparing them to a new set of K402 based MEHs I have in the works based on Chris' center prototype.
Im considering a K-402 as well, but I will build the horn from wood like the guy on the Australian forum.. How is your project going?

I like to sit somewhat close like you. Joachim Gerhard also prefers a different ratio for our holy triangle..

Im really curious how the new WE 300b's with graphene compare to TAKATSUKI

I wonder how the Radians with BE sound compared to the TAD's?

@NBPK402 @VDS Do you have perhaps directivity plots of the MEH K-420 vertical? (I can find them on the web)
I am considering building this design, and will likely to make the first cuts this week. But now I hesitate at the last moment to change the design a bit. I could also place the speaker vertically as a solution! (The limited sweet spot is not an issue for me.)
The reason is because I would like to experiment with Bacch crosstalk cancellation software. Then narrow directivity (laser like) is more important than 'wide' constant directivity.
Hence my interest in the vertical directivity behavior.
