With lower then rate frequency Fs is also is very simple. If you refuse to make own experiment and confirm the unloading the bass from horn make difference then try to look at the subjects purely intellectually: why you need a driver to reproduce lower frequency then horn can handle and to have more exertion if the whole point to have horn is to get EQ wish would lower the diaphragm exertion. 
Now it is clear! Thank you, Romy!Today I auditioned and measured GOTO with closed hole in back chamber. Mid-bass completely disappeared!
With closed back chamber it works efficiently only from 200Hz! So, I'm going to try it in my 200Hz LeCleach.
Regarding extra inches of LeCleach - in contrast with Tractix this extra inches allows to use this horn right from rate frequency - from 200Hz...looks like allows...I need to experiment to confirm it.

Still, I it is your system you can do whatever you want and you do not need to do it “right”. Juts one point I would like to make. At your site a person suggested to make 3-way time align horn system because to make 4-ways horn is superbly difficult. Well, I run 7-way horn system and I know how long time it took to me to realized many cons and pros. I do not suggest that I am “right” but I have my reasons besides my reasons.
I don't see any other "right" for me.
1. Standard HF driver covers 1000Hz plus region.
2. Horns can't produce right super HF, so the only option is RAAL to match horns sensitivity.
3,4. Upper bass and mid bass horns must be separated, because upper bass region sounds poor in long mid bass horn.
5. ULF is needed to cover 30Hz minus region.
6. Fundamental channel in needed, because using relatively long horn and relatively big and heavy diaphragm for the most loud and dense region of orchestra is not good.
So, 6 channels at least is the only "right" for me.But to get them time-aligned and crossovered right is really a challenge. I understand it.
And I very much appreciate your attention. You are an inventor of this concept and it is so good that you are sharing your experience!
