How many octaves from fs? We are taking about how many fractions of dB not octaves! Look for a threated:

…as a good start. 
I know this thread and was thinking to use your technique to adjust fs of Supravox's back chamber.As I understand the idea is to tune fs to find the best by ears.
But I don't see any explanation - why GOTO will not be properly loaded in say 160Hz horn because of low resonance ?
How resonance correlates with frequency of proper loading horn ?
 What the LeCleach will do with JBL2490? Do you have an extra 10 inch to waste in your vertical plane? Also, it is kind of funny that a guy who was crying about tonal beauty of GOTO drivers has anything to do with tone-neutered 2490…
I'm ok with tone of 2490 below 500Hz...for now...may be better driver exist, but no choice, unfortunately.Regarding additional LeCleach's inches - for now I have only HornResp models which you don't respect, I know. But model shows more impressive picture with this additional inches, so I have to try.

I do not like this idea. If you have 40-50Hz horn then you do not want it to beam into you from a short distance. You might get a better result if you flip the horns and point them to corners but they will read the wall too march and you would need to calibrate the back chamber of the horn in the position. Also, the corner-firing horn is tricky. Anyhow, if I had 20 by 20 room then I would not go for any 4”-entrance midbass, unless I could smash the walls 
What is your distance to mid-bass horn mouth ? 
PS; Name you images unlikely and identifiable.
 
Sure, no problem!
