Romy, thank you very much for very detailed explanation of your horn theory. Let me present some doubts about it. From physics basics when we have more than one springs (suspension, throat resistance, back chamber) we can consider it as one spring. That means, that the "symmetrical load to the diaphragm" concept is not solid. It is absolutely doesn't matter how symmetrical are front and back springs as at the end there is only one joint spring attached to the diaphragm with single resonance, of course. With back chamber you can tune it, yes. And finding optimal resonance for the mid-bass horn is reasonable. We can use this resonance to extend lower.
But I don't see any explanation of the "too low resonance problem of the upper-bass horn". Can you elaborate on this ?

I do not think you express any doubts but rather incorrect understanding.  More than one spring do not make one spring. This cal DC offset. Apply to input of your let day A/D + 3V DC and let me know if you recognize any difference in AC signal. The very same with diaphragm, you do not want diaphragm to have a contra-pressure in one direction leas then in another, this is how you get compression. 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. 

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.
