I got this new midbass horn to replace the Edgar 80Hz straight horn. It is made by Funktion-One and they claim it plays down to 90hz. I could not get it to play below 120Hz and I am trying to figure out why.

Impedance response

15" driver. The mouth is 39"x17". It is 34" deep from mouth to driver. Looking at the impedance sweep, there is a resonance at 80hz.
So the thing is that it sounds much better than the Edgar midbass but I cannot get it to play to 90Hz or even 100Hz, but I would like to. Because the sound is promising.
What is it that's preventing to play down to the claimed 90Hz? Too small back chamber? If that is the case I am willing to spend time and effort to enlarge the back chamber... Recommendations?
Thank you!Gera
