No dims, but just eyeball scaling using the driver sure makes them look like 500 Hz to me and of course the baffle will work with it too, just need more work to seal it up. Beautiful workmanship for sure!

I thought about something @GM said about the machining at the throat...
In the examples shown I could see no pics at the throats of those wood horns and that’s what is most concerning about the design. Maybe it’s great, but I have no idea...
In particular, his words i remember most are in reference to, and the importance of the entry of each cell and the partition between cells being free of acoustically reflective surfaces, also a classic Emerson, Lake, & Palmer tune...I thought about something @GM said about the machining at the throat...
Knife Edge.

Not all vegetables make good leaders.
Right, as critical as it is to seamlessly line up a 511/811 throat to the driver for max [smooth] HF extension, just think about a bunch of round/square/whatever throats dumping into a collector [low pass filter] that in turn adapts to the driver!
Once I learned from experience just how critical it is, I had a much greater appreciation that these huge horns/drivers could top 12 kHz at high SPL at a time when 8-9 kHz was the max available signal.
Wish I still had the pics of the super rare Jensen [32] cell/500 Hz horn; talk about attention to detail! Must have been made by pocket watch and/or 'sailing ship in bottle' craftsmen.

One thing I've noticed is that all these [installed] wood horns have super tweeters [not to mention they are typically offered by said wood horn manufacturers as a set], so assume the throats, etc., quality are more typical of large PA horns [~ 8 kHz upper limit].
