That is exactly what I was counting at and it has happened. Measuring this morning the resonance frequency I saw that it dropped from 43.7Hz to 38.7Hz. That is very very good, though I expected even more drop for a 2-3Hz during next week or two. My hope was based on the fact that my Vitavox drivers were sitting in a box 60 years and that their suspension has stiffened. Actively working in the horn the drivers get burn in a bit and the suspension get revived.

The 38.7Hz of primary resonance is already very good for me and if I have a back chamber 3-4 times of the side I do then I would be able to finish the back chamber in it’s final version. I will wait for another 2-3 weeks when the primary resonance will finally stabilize and then will make a decision if I extend back chamber, punch some holes in the current back chamber lid or to make the back chamber cover acoustically semi-transparent by other means.
